Description

A flaw was found in the ocfs2 file system within the Linux kernel. A local user could potentially trigger a deadlock due to an ABBA lock ordering violation between the `ocfs2_unlink` and `ocfs2_dio_end_io_write` functions. This race condition, caused by inconsistent lock acquisition order, could lead to a system hang, resulting in a Denial of Service (DoS).
