CVE-2026-99173

A vulnerability in the Linux kernel 's eventfs component allows a slab-use-after-free (UAF) condition. The issue occurs because tracefs_d_revalidate() reads an eventfs_inode while holding only an rcu_read_lock(), but the inode is freed after an SRCU grace period via release_ei(). Since the SRCU g...
