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

btrfs: fix inode list leak during backref walking at find_parent_nodes()

During backref walking, at find_parent_nodes(), if we are dealing with a
data extent and we get an error while resolving the indirect backrefs, at
resolve_indirect_refs(), or in the while loop that iterates over the refs
in the direct refs rbtree, we end up leaking the inode lists attached to
the direct refs we have in the direct refs rbtree that were not yet added
to the refs ulist passed as argument to find_parent_nodes(). Since they
were not yet added to the refs ulist and prelim_release() does not free
the lists, on error the caller can only free the lists attached to the
refs that were added to the refs ulist, all the remaining refs get their
inode lists never freed, therefore leaking their memory.

Fix this by having prelim_release() always free any attached inode list
to each ref found in the rbtree, and have find_parent_nodes() set the
ref's inode list to NULL once it transfers ownership of the inode list
to a ref added to the refs ulist passed to find_parent_nodes().

CVSS score: 3.3 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L)
Description: In the Linux kernel, the following vulnerability has been resolved:

gfs2: Check sb_bsize_shift after reading superblock

Fuzzers like to scribble over sb_bsize_shift but in reality it's very
unlikely that this field would be corrupted on its own. Nevertheless it
should be checked to avoid the possibility of messy mount errors due to
bad calculations. It's always a fixed value based on the block size so
we can just check that it's the expected value.

Tested with:

    mkfs.gfs2 -O -p lock_nolock /dev/vdb
    for i in 0 -1 64 65 32 33; do
        gfs2_edit -p sb field sb_bsize_shift $i /dev/vdb
        mount /dev/vdb /mnt/test && umount /mnt/test
    done

Before this patch we get a withdraw after

[   76.413681] gfs2: fsid=loop0.0: fatal: invalid metadata block
[   76.413681]   bh = 19 (type: exp=5, found=4)
[   76.413681]   function = gfs2_meta_buffer, file = fs/gfs2/meta_io.c, line = 492

and with UBSAN configured we also get complaints like

[   76.373395] UBSAN: shift-out-of-bounds in fs/gfs2/ops_fstype.c:295:19
[   76.373815] shift exponent 4294967287 is too large for 64-bit type 'long unsigned int'

After the patch, these complaints don't appear, mount fails immediately
and we get an explanation in dmesg.
Statement: This patch addresses an issue in GFS2 where the sb_bsize_shift field in the superblock was not validated before use. A corrupted or maliciously modified value could cause shift-out-of-bounds errors, leading to a kernel panic or undefined behavior during mount operations. By validating sb_bsize_shift, the kernel can fail gracefully with an error message instead of crashing.

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

net: ipv6: unexport __init-annotated seg6_hmac_init()

EXPORT_SYMBOL and __init is a bad combination because the .init.text
section is freed up after the initialization. Hence, modules cannot
use symbols annotated __init. The access to a freed symbol may end up
with kernel panic.

modpost used to detect it, but it has been broken for a decade.

Recently, I fixed modpost so it started to warn it again, then this
showed up in linux-next builds.

There are two ways to fix it:

  - Remove __init
  - Remove EXPORT_SYMBOL

I chose the latter for this case because the caller (net/ipv6/seg6.c)
and the callee (net/ipv6/seg6_hmac.c) belong to the same module.
It seems an internal function call in ipv6.ko.

CVSS score: 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
CWE: CWE-476
Description: In the Linux kernel, the following vulnerability has been resolved:

iommu/arm-smmu-v3: Don't unregister on shutdown

Similar to SMMUv2, this driver calls iommu_device_unregister() from the
shutdown path, which removes the IOMMU groups with no coordination
whatsoever with their users - shutdown methods are optional in device
drivers. This can lead to NULL pointer dereferences in those drivers'
DMA API calls, or worse.

Instead of calling the full arm_smmu_device_remove() from
arm_smmu_device_shutdown(), let's pick only the relevant function call -
arm_smmu_device_disable() - more or less the reverse of
arm_smmu_device_reset() - and call just that from the shutdown path.
CVE-2022-49786 (Moderate severity, published 2025-04-30)
CVSS score: 4.4 (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H)
Description: In the Linux kernel, the following vulnerability has been resolved:

blk-cgroup: properly pin the parent in blkcg_css_online

blkcg_css_online is supposed to pin the blkcg of the parent, but
397c9f46ee4d refactored things and along the way, changed it to pin the
css instead.  This results in extra pins, and we end up leaking blkcgs
and cgroups.
Statement: A resource leak was identified in blkcg_css_online() where the current css was pinned instead of its parent, leading to extra references and memory not being freed. This issue can only be triggered by privileged users with CAP_SYS_ADMIN rights and does not allow for privilege escalation or data leakage. The leak may slowly exhaust kernel memory in systems making frequent use of cgroups and block I/O throttling.
CVE-2022-1615 (Low severity, published 2022-07-26)
CVSS score: 5.1 (CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)
CWE: CWE-330
Description: A flaw was found in Samba. When the gnutls_rnd function is called, its return value is not verified, allowing it to give predictable random values when the call to the gnutls_rnd function fails.
CVE-2022-3628 (Moderate severity, published 2022-10-22)
CVSS score: 6.8 (CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CWE: CWE-120
Description: A buffer overflow flaw was found in the Linux kernel Broadcom Full MAC Wi-Fi driver. This issue occurs when a user connects to a malicious USB device. This can allow a local user to crash the system or escalate their privileges.
Mitigation: To mitigate this issue, prevent the brcmfmac module from being loaded. See https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically.
CVE-2022-0907 (Low severity, published 2022-03-10)
CVSS score: 5.5 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H)
CWE: CWE-476
Description: A NULL pointer dereference flaw was found in Libtiff. This flaw allows an attacker with a crafted TIFF file to cause a crash that leads to a denial of service.
Statement: None of the versions shipped with Red Hat Enterprise Linux are affected because vulnerable code is not present in our code-base.
CVE-2022-3782 (Important severity, published 2022-12-11)
CVSS score: 8.1 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N)
CWE: CWE-22
Description: A flaw was found in Keycloak, where it does not properly validate URLs included in a redirect. An attacker can use this flaw to construct a malicious request to bypass validation and access other URLs and potentially sensitive information within the domain or possibly conduct further attacks. This flaw affects any client that utilizes a wildcard in the Valid Redirect URIs field.
Statement: Red Hat Build of Quarkus is not impacted as this CVE affects the server-side Keycloak execution but Quarkus only acts as a Keycloak client in its quarkus-keycloak-authorization extension. For this reason Quarkus is marked with Low impact.
CVE-2022-1245 (Moderate severity, published 2022-04-18)
CVSS score: 8 (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H)
CWE: CWE-639
Description: A privilege escalation flaw was found in the token exchange feature of keycloak. Missing authorization allows a client application holding a valid access token to exchange tokens for any target client by passing the client_id of the target. This could allow a client to gain unauthorized access to additional services.
Statement: The token exchange feature is currently in technology preview and is not fully supported. Please see the documentation for more information on this feature: https://access.redhat.com/documentation/en-us/red_hat_single_sign-on/7.5/html/securing_applications_and_services_guide/token-exchange
