Description
This security bulletin contains information about 2 vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2026-43499)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 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/E:U/U:Clear
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to use-after-free in remove_waiter() when rolling back a proxy lock from futex_requeue(). A local user can trigger the affected rtmutex slowlock and proxy-lock rollback path to cause a denial of service.
The issue can leave waiter task state uncleared and operate on the wrong top priority waiter task.
2) NULL pointer dereference (CVE-ID: CVE-2026-53166)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: 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/E:U/U:Clear
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to a NULL pointer dereference in remove_waiter() in the futex requeue logic when handling FUTEX_CMP_REQUEUE_PI operations that requeue a non-top waiter which already owns the target PI futex. A local user can trigger a self-deadlock condition to cause a denial of service.
