Description
A flaw was found in the Linux kernel's Btrfs file system. When path resolution encounters an error while reporting scrub warnings, the kernel fails to release an acquired reference to the file system root structure. A local user could trigger this condition during file system scrubbing to cause a resource leak, potentially leading to resource exhaustion or a Denial of Service (DoS).
