CVE-2026-99250

The Linux kernel contains a vulnerability where NBCON kthreads for console printing are started too early during boot using early_initcall(). Because these kthreads asynchronously enable or disable interrupts, they can interfere with early SMP setup on certain hardware platforms, leading to syste...

CVE-2026-78118 Race condition on kernel wait queues: unlocked z_waitq_head() read in the timer expiration handler can yield a stale or sentinel thread pointer on SMP

The kernel helper zwaitqhead kernel/include/waitq.h reads the head of a thread wait queue, but on SMP systems it was called from several places without holding the scheduler spinlock schedspinlock that serializes wait-queue mutation. The consequential call site is ztimerexpirationhandler in...

CVE-2026-78118

The Zephyr RTOS kernel contains a race condition in the z_waitq_head() helper function (kernel/include/wait_q.h). On SMP systems , this helper was called from several locations—notably z_timer_expiration_handler() in kernel/timer.c—without holding the _sched_spinlock, which is required to seriali...
