A deadlock vulnerability in the Linux kernel's memory management subsystem was resolved. The issue involved the function __kfree_rcu_sheaf() waking up kswapd while holding a raw spinlock (pi_lock), which could lead to a circular locking dependency and deadlock. This deadlock was difficult to reproduce and was verified using a modified kernel with lock dependency detection. The vulnerability was fixed by ensuring kfree_rcu() does not wake up kswapd under pi_lock. Join the discussion | GCVE Database | 10/18/2026, 18:32:04 UTC Added: 10/18/2026, 19:40:26 UTC |
