CVSS score: 6 (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:H)
CWE: CWE-416
Description: In the Linux kernel, the following vulnerability has been resolved:

blk-throttle: Set BIO_THROTTLED when bio has been throttled

1.In current process, all bio will set the BIO_THROTTLED flag
after __blk_throtl_bio().

2.If bio needs to be throttled, it will start the timer and
stop submit bio directly. Bio will submit in
blk_throtl_dispatch_work_fn() when the timer expires.But in
the current process, if bio is throttled. The BIO_THROTTLED
will be set to bio after timer start. If the bio has been
completed, it may cause use-after-free blow.

CWE: CWE-444
Description: A flaw was found in Apache Tomcat. If the server is configured to ignore invalid HTTP headers, the server does not reject a request containing an invalid content-length header, making it vulnerable to a request smuggling attack.
Statement: Red Hat Satellite does not include the affected Apache Tomcat, however, Tomcat is shipped with Red Hat Enterprise Linux and consumed by the Candlepin component of Satellite. Red Hat Satellite users are therefore advised to check the impact state of Red Hat Enterprise Linux, since any necessary fixes will be distributed through the platform.

Tomcat requires a non-standard setting of rejectIllegalHeader = false. Also it demands Tomcat to be behind a proxy reverse proxy that also failed to reject the request with the invalid
header. A malicious attacker would need time and efforts to go through the environment and jeopardize the environment by accessing protected data. Hence the CVSS score of 4.8.

Description: In the Linux kernel, the following vulnerability has been resolved:

net: dsa: don't leak tagger-owned storage on switch driver unbind

In the initial commit dc452a471dba ("net: dsa: introduce tagger-owned
storage for private and shared data"), we had a call to
tag_ops->disconnect(dst) issued from dsa_tree_free(), which is called at
tree teardown time.

There were problems with connecting to a switch tree as a whole, so this
got reworked to connecting to individual switches within the tree. In
this process, tag_ops->disconnect(ds) was made to be called only from
switch.c (cross-chip notifiers emitted as a result of dynamic tag proto
changes), but the normal driver teardown code path wasn't replaced with
anything.

Solve this problem by adding a function that does the opposite of
dsa_switch_setup_tag_protocol(), which is called from the equivalent
spot in dsa_switch_teardown(). The positioning here also ensures that we
won't have any use-after-free in tagging protocol (*rcv) ops, since the
teardown sequence is as follows:

dsa_tree_teardown
-> dsa_tree_teardown_master
   -> dsa_master_teardown
      -> unsets master->dsa_ptr, making no further packets match the
         ETH_P_XDSA packet type handler
-> dsa_tree_teardown_ports
   -> dsa_port_teardown
      -> dsa_slave_destroy
         -> unregisters DSA net devices, there is even a synchronize_net()
            in unregister_netdevice_many()
-> dsa_tree_teardown_switches
   -> dsa_switch_teardown
      -> dsa_switch_teardown_tag_protocol
         -> finally frees the tagger-owned storage

can_put_echo_skb() for the m_can version 3.0.x directly before the
start of the xmit in hardware, similar to the 3.1.x branch.

Description: A vulnerability was found in BlueZ. This flaw allows physically proximate attackers to cause a denial of service due to malformed and invalid capabilities processed in profiles/audio/avdtp.c.
CVE-2022-49625 (Low severity, published 2025-02-25)
CVSS score: 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
Description: In the Linux kernel, the following vulnerability has been resolved:

sfc: fix kernel panic when creating VF

When creating VFs a kernel panic can happen when calling to
efx_ef10_try_update_nic_stats_vf.

When releasing a DMA coherent buffer, sometimes, I don't know in what
specific circumstances, it has to unmap memory with vunmap. It is
disallowed to do that in IRQ context or with BH disabled. Otherwise, we
hit this line in vunmap, causing the crash:
  BUG_ON(in_interrupt());

This patch reenables BH to release the buffer.

Log messages when the bug is hit:

CVE-2022-48937 (Moderate severity, published 2024-08-21)
CVSS score: 3.3 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L)
CWE: CWE-667
Description: A vulnerability was found in the Linux kernel’s io_uring subsystem, specifically within the io_add_buffers() function. This issue could lead to soft lockups by repeatedly invoking kmalloc() in a loop of around 65,535 iterations, especially when debugging features like KASAN are enabled. Symptoms included the kernel watchdog reporting that a CPU was stuck for extended periods.
Statement: Red Hat Enterprise Linux is not vulnerable to this CVE, as it does not affect the versions or configurations of the Linux kernel used in its distributions.
Mitigation: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
CVE-2022-23829 (Important severity, published 2024-06-11)
CVSS score: 8.2 (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H)
Description: A flaw was found in AMD SPI. The protection features may allow a malicious attacker with Ring0 kernel mode access to bypass the native System Management Mode (SMM) ROM protections.
Mitigation: Platform BIOS changes are needed to enable AMD ROM Armor.

Please contact OEM supplier for the BIOS update.
CVE-2022-31117 (Moderate severity, published 2022-07-01)
CVSS score: 5.9 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)
CWE: CWE-415
Description: UltraJSON is a fast JSON encoder and decoder written in pure C with bindings for Python 3.7+. In versions prior to 5.4.0 an error occurring while reallocating a buffer for string decoding can cause the buffer to get freed twice. Due to how UltraJSON uses the internal decoder, this double free is impossible to trigger from Python. This issue has been resolved in version 5.4.0 and all users should upgrade to UltraJSON 5.4.0. There are no known workarounds for this issue.
CVE-2022-50111 (Low severity, published 2025-06-17)

ASoC: mt6359: Fix refcount leak bug

In mt6359_parse_dt() and mt6359_accdet_parse_dt(), we should call
of_node_put() for the reference returned by of_get_child_by_name()
which has increased the refcount.
