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...
