In the Linux kernel, the following vulnerability has been resolved: rqspinlock: Reset tail when preserving queue on deadlock Currently, the… (CVE-2026-74686)CVE-2026-74686 0 A vulnerability in the Linux kernel's rqspinlock implementation related to deadlock handling has been resolved. The issue involves improper resetting of the tail pointer in the waiter queue during deadlock detection, which can cause intermittent stalls or indefinite waits in specific ABBA deadlock scenarios. This occurs because the final waiter in the queue waits indefinitely for a next waiter that may never arrive, leading to potential system stalls. The fix adjusts the logic to properly reset the tail and signal the next waiter, preventing these stalls.
