Description

A flaw was found in the Linux kernel's fsnotify subsystem. When a parent directory stops watching its children, a race condition can occur during the clearing of PARENT_WATCHED flags. This contention on the inode->i_lock can lead to system unresponsiveness or softlockups, effectively causing a Denial of Service (DoS) for a local user.
