CVE-2026-53275

In the Linux kernel, the following vulnerability has been resolved: ipv6: mcast: Fix use-after-free when processing MLD queries When processing an MLD query, a pointer to the multicast group address is retrieved when initially parsing the packet. This pointer is later dereferenced without being reloaded despite the fact that the skb header might have been reallocated following the pskb_may_pull() calls, leading to a use-after-free [1]. Fix by copying the multicast group address when the packet is initially parsed.

Security Fix(es):

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

wifi: mac80211: check tdls flag in ieee80211_tdls_oper

When NL80211_TDLS_ENABLE_LINK is called, the code only checks if the station exists but not whether it is actually a TDLS station. This allows the operation to proceed for non-TDLS stations, causing unintended side effects like modifying channel context and HT protection before failing.

Add a check for sta->sta.tdls early in the ENABLE_LINK case, before any side effects occur, to ensure the operation is only allowed for actual TDLS peers.(CVE-2026-43052)

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

wifi: brcmfmac: validate bsscfg indices in IF events

brcmf_fweh_handle_if_event() validates the firmware-provided interface index before it touches drvr->iflist[], but it still uses the raw bsscfgidx field as an array index without a matching range check.

Reject IF events whose bsscfg index does not fit in drvr->iflist[] before indexing the interface array.

add missing wifi prefix

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

HID: roccat: fix use-after-free in roccat_report_event

roccat_report_event() iterates over the device->readers list without holding the readers_lock. This allows a concurrent roccat_release() to remove and free a reader while it's still being accessed, leading to a use-after-free.

Protect the readers list traversal with the readers_lock mutex.(CVE-2026-43111)

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

drm/amdkfd: Fix out-of-bounds write in kfd_event_page_set()

The kfd_event_page_set() function writes KFD_SIGNAL_EVENT_LIMIT * 8 bytes via memset without checking the buffer size parameter. This allows unprivileged userspace to trigger an out-of bounds kernel memory write by passing a small buffer, leading to potential privilege escalation.(CVE-2026-43206)

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

ext4: drop extent cache after doing PARTIAL_VALID1 zeroout

When splitting an unwritten extent in the middle and converting it to initialized in ext4_split_extent() with the EXT4_EXT_MAY_ZEROOUT and EXT4_EXT_DATA_VALID2 flags set, it could leave a stale unwritten extent.

Assume we have an unwritten file and buffered write in the middle of it without dioread_nolock enabled, it will allocate blocks as written extent.

   0  A      B  N
   [UUUUUUUUUUUU] on-disk extent      U: unwritten extent
   [UUUUUUUUUUUU] extent status tree
   [--DDDDDDDD--]                     D: valid data
      |<-  ->| ----> this range needs to be initialized

ext4_split_extent() first try to split this extent at B with EXT4_EXT_DATA_PARTIAL_VALID1 and EXT4_EXT_MAY_ZEROOUT flag set, but ext4_split_extent_at() failed to split this extent due to temporary lack of space. It zeroout B to N and leave the entire extent as unwritten.

   0  A      B  N
   [UUUUUUUUUUUU] on-disk extent
   [UUUUUUUUUUUU] extent status tree
   [--DDDDDDDDZZ]                     Z: zeroed data

ext4_split_extent() then try to split this extent at A with EXT4_EXT_DATA_VALID2 flag set. This time, it split successfully and leave an written extent from A to N.

   0  A      B  N
   [UUWWWWWWWWWW] on-disk extent      W: written extent
   [UUUUUUUUUUUU] extent status tree
   [--DDDDDDDDZZ]

Finally ext4_map_create_blocks() only insert extent A to B to the extent status tree, and leave an stale unwritten extent in the status tree.

   0  A      B  N
   [UUWWWWWWWWWW] on-disk extent      W: written extent
   [UUWWWWWWWWUU] extent status tree
   [--DDDDDDDDZZ]

Fix this issue by always cached extent status entry after zeroing out the second part.(CVE-2026-45892)

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

ipv6: mcast: Fix use-after-free when processing MLD queries

When processing an MLD query, a pointer to the multicast group address is retrieved when initially parsing the packet. This pointer is later dereferenced without being reloaded despite the fact that the skb header might have been reallocated following the pskb_may_pull() calls, leading to a use-after-free [1].

Fix by copying the multicast group address when the packet is initially parsed.

It was discovered that some Arm processors could complete a broadcast translation lookaside buffer (TLB) invalidation before memory writes made through the invalidated translation were globally observed. A local attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing memory protections or escalating privileges. (CVE-2025-10263)

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems:

It was discovered that some Arm processors could complete a broadcast translation lookaside buffer (TLB) invalidation before memory writes made through the invalidated translation were globally observed. A local attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing memory protections or escalating privileges. (CVE-2025-10263)

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems:
