Linux kernel is vulnerable to privilege escalation. A race condition was found in the Linux kernel, present since v3.14-rc1 through v4.12. The race happens between threads of inotify_handle_event() and vfs_rename() while running the rename operation against the same file. As a result of the race the next slab data or the slab’s free list pointer can be corrupted with attacker-controlled data, which may lead to the privilege escalation.
