Description

This security bulletin contains information about 4 vulnerabilities.


1) NULL pointer dereference (CVE-ID: CVE-2025-40321)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to NULL pointer dereference within the drivers/net/wireless/broadcom/brcm80211/brcmfmac/p2p.h. A local user can perform a denial of service (DoS) attack.


2) Out-of-bounds read (CVE-ID: CVE-2026-74291)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a local user to disclose sensitive information.

The vulnerability exists due to an out-of-bounds read in the ASoC topology parser when parsing a malformed topology blob with non-NUL-terminated PCM, DAI, or stream capability name fields. A local user can supply a specially crafted topology blob to disclose sensitive information.


3) Improper locking (CVE-ID: CVE-2026-80534)

CWE-ID: CWE-667 - Improper Locking

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to improper lock release in xfs_dq_get_next_id when handling an error from xfs_iread_extents. A local user can trigger the error condition during quota operations to cause a denial of service.

The issue can leave the quota inode locked, causing subsequent quota operations to hang.


4) Double free (CVE-ID: CVE-2026-80698)

CWE-ID: CWE-415 - Double Free

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to a double free in the idxd wq, engine, and group device setup and cleanup paths when handling device reference release during error handling and cleanup. A local user can trigger affected cleanup paths to cause a denial of service.

The issue occurs when put_device() drops the device reference count to zero and invokes the release callbacks, while the same allocations are also freed explicitly.
