0 CVE-2026-78118 is a race condition vulnerability in the Zephyr kernel's wait queue handling on SMP (multi-CPU) systems. It arises because the kernel helper z_waitq_head() reads the head of a thread wait queue without holding the necessary scheduler spinlock, leading to potential use-after-free and out-of-bounds writes. This can cause scheduler state corruption or kernel crashes. Exploitation requires local code execution on a multi-CPU system and precise timing. The vulnerability affects Zephyr versions from 2.2.0 up to but not including 4.5.0. Join the discussion | CVE Database V5 | 10/21/2026, 18:19:32 UTC Added: 10/21/2026, 18:31:45 UTC |
