Description
A flaw was found in the Linux kernel's XFS file system. A local user could cause a Denial of Service (DoS) due to a memory leak in the directory tree scrub and repair mechanisms. When an error occurs while appending a directory name to a path, the kernel fails to release previously allocated inode tracking data. Repeated occurrences can lead to kernel memory exhaustion and degrade overall system availability.
