CVE-2026-46106

CVE-2026-46106 concerns the Linux kernel eventfs remount race. The root cause is a race where eventfs_inodes are traversed while remounts are performed, due to mixing rcu_read_lock usage with SRCU and not holding eventfs_mutex during the critical walk. The fix (commit 340f0c7067a9) updates the ev...

kernel: mm: thp: deny THP for files on anonymous inodes

A flaw was found in the Linux kernel's Transparent Huge Pages THP mechanism. This vulnerability occurs because the filethpenabled function incorrectly allows THP for files on anonymous inodes, which are not designed for this feature. An attacker could potentially exploit this by manipulating...
