Description
A flaw was found in the Linux kernel's XFS file system. When an input/output (I/O) error occurs while writing cached data buffers to disk during b-tree preparation, the kernel fails to release an allocated buffer. A local user performing file system operations could trigger this condition to leak locked buffers, leading to resource exhaustion and a denial of service (DoS).
