CVE-2026-98939

The Linux kernel contains a vulnerability where a possible deadlock occurs on systems with a discrete GPU . The root cause is an x86 commit that introduced an mmap_read_lock() in kernel page protection munging code. This creates a circular locking dependency because the huge vmap code holds the s...

CVE-2026-98818

The Linux kernel contains a deadlock vulnerability in the mm/slab component. The issue arises because kfree_rcu() can be called while holding the pi_lock (a raw spinlock in the scheduler). If kfree_rcu() attempts to allocate memory using __GFP_KSWAPD_RECLAIM , it can wake up kswapd , which then t...
