In the Linux kernel, the following vulnerability has been resolved: futex: Prevent robust futex exit race some more A robust futex unlock stores 0… (CVE-2026-74658)CVE-2026-74658 0 A vulnerability in the Linux kernel's futex implementation related to robust futex exit race conditions has been resolved. The issue involves a race condition where waiters on a futex can be left sleeping indefinitely due to lost wake notifications when a woken waiter is killed before it can act. This leads to a scenario where remaining waiters never get woken, causing potential indefinite blocking. The fix augments the robust list exit processing to ensure extra wakeups occur if the futex is owned by another thread but the FUTEX_WAITERS bit is not set. This patch addresses a known shortcoming but does not fully resolve all related futex contention issues, which are being addressed in ongoing kernel development.
