CVE-2025-37809 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: usb: typec: class: Fix NULL pointer access Concurrent calls to typec_partner_unlink_device can lead to a NULL pointer dereference. This patch adds a mutex to protect USB device pointers and prevent this issue. The same mutex protects both the device pointers and the partner device registration.
CVE-2025-3781 (severity: MEDIUM, weakness: CWE-79)
The Raisely Donation Form plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's raisely_donation_form shortcode in all versions up to, and including, 1.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
CVE-2025-37810 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: usb: dwc3: gadget: check that event count does not exceed event buffer length The event count is read from register DWC3_GEVNTCOUNT. There is a check for the count being zero, but not for exceeding the event buffer length. Check that event count does not exceed event buffer length, avoiding an out-of-bounds access when memcpy'ing the event. Crash log: Unable to handle kernel paging request at virtual address ffffffc0129be000 pc : __memcpy+0x114/0x180 lr : dwc3_check_event_buf+0xec/0x348 x3 : 0000000000000030 x2 : 000000000000dfc4 x1 : ffffffc0129be000 x0 : ffffff87aad60080 Call trace: __memcpy+0x114/0x180 dwc3_interrupt+0x24/0x34
CVE-2025-37811 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: usb: chipidea: ci_hdrc_imx: fix usbmisc handling usbmisc is an optional device property so it is totally valid for the corresponding data->usbmisc_data to have a NULL value. Check that before dereferencing the pointer. Found by Linux Verification Center (linuxtesting.org) with Svace static analysis tool.
CVE-2025-37812 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: usb: cdns3: Fix deadlock when using NCM gadget The cdns3 driver has the same NCM deadlock as fixed in cdnsp by commit 58f2fcb3a845 ("usb: cdnsp: Fix deadlock issue during using NCM gadget"). Under PREEMPT_RT the deadlock can be readily triggered by heavy network traffic, for example using "iperf --bidir" over NCM ethernet link. The deadlock occurs because the threaded interrupt handler gets preempted by a softirq, but both are protected by the same spinlock. Prevent deadlock by disabling softirq during threaded irq handler.
CVE-2025-37813 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: usb: xhci: Fix invalid pointer dereference in Etron workaround This check is performed before prepare_transfer() and prepare_ring(), so enqueue can already point at the final link TRB of a segment. And indeed it will, some 0.4% of times this code is called. Then enqueue + 1 is an invalid pointer. It will crash the kernel right away or load some junk which may look like a link TRB and cause the real link TRB to be replaced with a NOOP. This wouldn't end well. Use a functionally equivalent test which doesn't dereference the pointer and always gives correct result. Something has crashed my machine twice in recent days while playing with an Etron HC, and a control transfer stress test ran for confirmation has just crashed it again. The same test passes with this patch applied.
CVE-2025-37815 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: misc: microchip: pci1xxxx: Fix Kernel panic during IRQ handler registration Resolve kernel panic while accessing IRQ handler associated with the generated IRQ. This is done by acquiring the spinlock and storing the current interrupt state before handling the interrupt request using generic_handle_irq. A previous fix patch was submitted where 'generic_handle_irq' was replaced with 'handle_nested_irq'. However, this change also causes the kernel panic where after determining which GPIO triggered the interrupt and attempting to call handle_nested_irq with the mapped IRQ number, leads to a failure in locating the registered handler.
CVE-2025-37816 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: mei: vsc: Fix fortify-panic caused by invalid counted_by() use gcc 15 honors the __counted_by(len) attribute on vsc_tp_packet.buf[] and the vsc-tp.c code is using this in a wrong way. len does not contain the available size in the buffer, it contains the actual packet length *without* the crc. So as soon as vsc_tp_xfer() tries to add the crc to buf[] the fortify-panic handler gets triggered: [ 80.842193] memcpy: detected buffer overflow: 4 byte write of buffer size 0 [ 80.842243] WARNING: CPU: 4 PID: 272 at lib/string_helpers.c:1032 __fortify_report+0x45/0x50 ... [ 80.843175] __fortify_panic+0x9/0xb [ 80.843186] vsc_tp_xfer.cold+0x67/0x67 [mei_vsc_hw] [ 80.843210] ? seqcount_lockdep_reader_access.constprop.0+0x82/0x90 [ 80.843229] ? lockdep_hardirqs_on+0x7c/0x110 [ 80.843250] mei_vsc_hw_start+0x98/0x120 [mei_vsc] [ 80.843270] mei_reset+0x11d/0x420 [mei] The easiest fix would be to just drop the counted-by but with the exception of the ack buffer in vsc_tp_xfer_helper() which only contains enough room for the packet-header, all other uses of vsc_tp_packet always use a buffer of VSC_TP_MAX_XFER_SIZE bytes for the packet. Instead of just dropping the counted-by, split the vsc_tp_packet struct definition into a header and a full-packet definition and use a fixed size buf[] in the packet definition, this way fortify-source buffer overrun checking still works when enabled.
CVE-2025-37817 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: mcb: fix a double free bug in chameleon_parse_gdd() In chameleon_parse_gdd(), if mcb_device_register() fails, 'mdev' would be released in mcb_device_register() via put_device(). Thus, goto 'err' label and free 'mdev' again causes a double free. Just return if mcb_device_register() fails.
CVE-2025-37818 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: LoongArch: Return NULL from huge_pte_offset() for invalid PMD LoongArch's huge_pte_offset() currently returns a pointer to a PMD slot even if the underlying entry points to invalid_pte_table (indicating no mapping). Callers like smaps_hugetlb_range() fetch this invalid entry value (the address of invalid_pte_table) via this pointer. The generic is_swap_pte() check then incorrectly identifies this address as a swap entry on LoongArch, because it satisfies the "!pte_present() && !pte_none()" conditions. This misinterpretation, combined with a coincidental match by is_migration_entry() on the address bits, leads to kernel crashes in pfn_swap_entry_to_page(). Fix this at the architecture level by modifying huge_pte_offset() to check the PMD entry's content using pmd_none() before returning. If the entry is invalid (i.e., it points to invalid_pte_table), return NULL instead of the pointer to the slot.
CVE-2025-37819 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v2m: Prevent use after free of gicv2m_get_fwnode() With ACPI in place, gicv2m_get_fwnode() is registered with the pci subsystem as pci_msi_get_fwnode_cb(), which may get invoked at runtime during a PCI host bridge probe. But, the call back is wrongly marked as __init, causing it to be freed, while being registered with the PCI subsystem and could trigger: Unable to handle kernel paging request at virtual address ffff8000816c0400 gicv2m_get_fwnode+0x0/0x58 (P) pci_set_bus_msi_domain+0x74/0x88 pci_register_host_bridge+0x194/0x548 This is easily reproducible on a Juno board with ACPI boot. Retain the function for later use.
CVE-2025-3782 (severity: MEDIUM, weakness: CWE-79)
The Cision Block plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘id’ parameter in all versions up to, and including, 4.3.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
CVE-2025-37820 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: xen-netfront: handle NULL returned by xdp_convert_buff_to_frame() The function xdp_convert_buff_to_frame() may return NULL if it fails to correctly convert the XDP buffer into an XDP frame due to memory constraints, internal errors, or invalid data. Failing to check for NULL may lead to a NULL pointer dereference if the result is used later in processing, potentially causing crashes, data corruption, or undefined behavior. On XDP redirect failure, the associated page must be released explicitly if it was previously retained via get_page(). Failing to do so may result in a memory leak, as the pages reference count is not decremented.
CVE-2025-37821 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: sched/eevdf: Fix se->slice being set to U64_MAX and resulting crash There is a code path in dequeue_entities() that can set the slice of a sched_entity to U64_MAX, which sometimes results in a crash. The offending case is when dequeue_entities() is called to dequeue a delayed group entity, and then the entity's parent's dequeue is delayed. In that case: 1. In the if (entity_is_task(se)) else block at the beginning of dequeue_entities(), slice is set to cfs_rq_min_slice(group_cfs_rq(se)). If the entity was delayed, then it has no queued tasks, so cfs_rq_min_slice() returns U64_MAX. 2. The first for_each_sched_entity() loop dequeues the entity. 3. If the entity was its parent's only child, then the next iteration tries to dequeue the parent. 4. If the parent's dequeue needs to be delayed, then it breaks from the first for_each_sched_entity() loop _without updating slice_. 5. The second for_each_sched_entity() loop sets the parent's ->slice to the saved slice, which is still U64_MAX. This throws off subsequent calculations with potentially catastrophic results. A manifestation we saw in production was: 6. In update_entity_lag(), se->slice is used to calculate limit, which ends up as a huge negative number. 7. limit is used in se->vlag = clamp(vlag, -limit, limit). Because limit is negative, vlag > limit, so se->vlag is set to the same huge negative number. 8. In place_entity(), se->vlag is scaled, which overflows and results in another huge (positive or negative) number. 9. The adjusted lag is subtracted from se->vruntime, which increases or decreases se->vruntime by a huge number. 10. pick_eevdf() calls entity_eligible()/vruntime_eligible(), which incorrectly returns false because the vruntime is so far from the other vruntimes on the queue, causing the (vruntime - cfs_rq->min_vruntime) * load calulation to overflow. 11. Nothing appears to be eligible, so pick_eevdf() returns NULL. 12. pick_next_entity() tries to dereference the return value of pick_eevdf() and crashes. Dumping the cfs_rq states from the core dumps with drgn showed tell-tale huge vruntime ranges and bogus vlag values, and I also traced se->slice being set to U64_MAX on live systems (which was usually "benign" since the rest of the runqueue needed to be in a particular state to crash). Fix it in dequeue_entities() by always setting slice from the first non-empty cfs_rq.
CVE-2025-37822 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: riscv: uprobes: Add missing fence.i after building the XOL buffer The XOL (execute out-of-line) buffer is used to single-step the replaced instruction(s) for uprobes. The RISC-V port was missing a proper fence.i (i$ flushing) after constructing the XOL buffer, which can result in incorrect execution of stale/broken instructions. This was found running the BPF selftests "test_progs: uprobe_autoattach, attach_probe" on the Spacemit K1/X60, where the uprobes tests randomly blew up.
CVE-2025-37823 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: net_sched: hfsc: Fix a potential UAF in hfsc_dequeue() too Similarly to the previous patch, we need to safe guard hfsc_dequeue() too. But for this one, we don't have a reliable reproducer.
CVE-2025-37825 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: nvmet: fix out-of-bounds access in nvmet_enable_port When trying to enable a port that has no transport configured yet, nvmet_enable_port() uses NVMF_TRTYPE_MAX (255) to query the transports array, causing an out-of-bounds access: [ 106.058694] BUG: KASAN: global-out-of-bounds in nvmet_enable_port+0x42/0x1da [ 106.058719] Read of size 8 at addr ffffffff89dafa58 by task ln/632 [...] [ 106.076026] nvmet: transport type 255 not supported Since commit 200adac75888, NVMF_TRTYPE_MAX is the default state as configured by nvmet_ports_make(). Avoid this by checking for NVMF_TRTYPE_MAX before proceeding.
CVE-2025-37826 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: scsi: ufs: core: Add NULL check in ufshcd_mcq_compl_pending_transfer() Add a NULL check for the returned hwq pointer by ufshcd_mcq_req_to_hwq(). This is similar to the fix in commit 74736103fb41 ("scsi: ufs: core: Fix ufshcd_abort_one racing issue").
CVE-2025-37828 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: scsi: ufs: mcq: Add NULL check in ufshcd_mcq_abort() A race can occur between the MCQ completion path and the abort handler: once a request completes, __blk_mq_free_request() sets rq->mq_hctx to NULL, meaning the subsequent ufshcd_mcq_req_to_hwq() call in ufshcd_mcq_abort() can return a NULL pointer. If this NULL pointer is dereferenced, the kernel will crash. Add a NULL check for the returned hwq pointer. If hwq is NULL, log an error and return FAILED, preventing a potential NULL-pointer dereference. As suggested by Bart, the ufshcd_cmd_inflight() check is removed. This is similar to the fix in commit 74736103fb41 ("scsi: ufs: core: Fix ufshcd_abort_one racing issue"). This is found by our static analysis tool KNighter.
CVE-2025-37829 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: cpufreq: scpi: Fix null-ptr-deref in scpi_cpufreq_get_rate() cpufreq_cpu_get_raw() can return NULL when the target CPU is not present in the policy->cpus mask. scpi_cpufreq_get_rate() does not check for this case, which results in a NULL pointer dereference.
CVE-2025-3783 (severity: MEDIUM, weakness: CWE-284)
A vulnerability classified as critical was found in SourceCodester Web-based Pharmacy Product Management System 1.0. Affected by this vulnerability is an unknown functionality of the file /add-product.php. The manipulation of the argument Avatar leads to unrestricted upload. The attack can be launched remotely. The exploit has been disclosed to the public and may be used.
CVE-2025-37830 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: cpufreq: scmi: Fix null-ptr-deref in scmi_cpufreq_get_rate() cpufreq_cpu_get_raw() can return NULL when the target CPU is not present in the policy->cpus mask. scmi_cpufreq_get_rate() does not check for this case, which results in a NULL pointer dereference. Add NULL check after cpufreq_cpu_get_raw() to prevent this issue.
CVE-2025-37831 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: cpufreq: apple-soc: Fix null-ptr-deref in apple_soc_cpufreq_get_rate() cpufreq_cpu_get_raw() can return NULL when the target CPU is not present in the policy->cpus mask. apple_soc_cpufreq_get_rate() does not check for this case, which results in a NULL pointer dereference.
CVE-2025-37832 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: cpufreq: sun50i: prevent out-of-bounds access A KASAN enabled kernel reports an out-of-bounds access when handling the nvmem cell in the sun50i cpufreq driver: ================================================================== BUG: KASAN: slab-out-of-bounds in sun50i_cpufreq_nvmem_probe+0x180/0x3d4 Read of size 4 at addr ffff000006bf31e0 by task kworker/u16:1/38 This is because the DT specifies the nvmem cell as covering only two bytes, but we use a u32 pointer to read the value. DTs for other SoCs indeed specify 4 bytes, so we cannot just shorten the variable to a u16. Fortunately nvmem_cell_read() allows to return the length of the nvmem cell, in bytes, so we can use that information to only access the valid portion of the data. To cover multiple cell sizes, use memcpy() to copy the information into a zeroed u32 buffer, then also make sure we always read the data in little endian fashion, as this is how the data is stored in the SID efuses.
CVE-2025-37833 (severity: None, weakness: NVD-CWE-Other)
In the Linux kernel, the following vulnerability has been resolved: net/niu: Niu requires MSIX ENTRY_DATA fields touch before entry reads Fix niu_try_msix() to not cause a fatal trap on sparc systems. Set PCI_DEV_FLAGS_MSIX_TOUCH_ENTRY_DATA_FIRST on the struct pci_dev to work around a bug in the hardware or firmware. For each vector entry in the msix table, niu chips will cause a fatal trap if any registers in that entry are read before that entries' ENTRY_DATA register is written to. Testing indicates writes to other registers are not sufficient to prevent the fatal trap, however the value does not appear to matter. This only needs to happen once after power up, so simply rebooting into a kernel lacking this fix will NOT cause the trap.

Reclaim process will put the hwpoisoned page back to lru. 2) The process that maps the hwpoisoned page exits, the page is deleted the page will never be freed and will be in the lru forever. 3) If we trigger a reclaim again and tries to reclaim the page, add_to_swap() will trigger VM_BUG_ON_FOLIO due to the uptodate flag is cleared. To fix it, skip the hwpoisoned page in shrink_folio_list(). Besides, the hwpoison folio may not be unmapped by hwpoison_user_mappings() yet, unmap it in shrink_folio_list(), otherwise the folio will fail to be unmaped by hwpoison_user_mappings() since the folio isn't in lru list.
