CVE-2026-90003

CVE-2026-90003 is a use-after-free in the Linux kernel's futex subsystem, triggered on PREEMPT_RT when a FUTEX_CMP_REQUEUE_PI operation races with a waiter's early wakeup (timeout or signal). The requeue task calls rcuwait_wake_up() after the waiter has already left the syscall and freed its stac...

CVE-2026-64073: Use After Free

In the Linux kernel, the following vulnerability has been resolved: irqwork: Fix use-after-free in irqworksingle on PREEMPTRT On PREEMPTRT, non-HARD irqwork runs in per-CPU kthreads via runirqworkd, so irqworksync uses rcuwait to wait for BUSY==0. After irqworksingle clears BUSY via atomiccmpxchg...
