The ocfs2_setattr function in fs/ocfs2/file.c in the Linux kernel before 4.14.2 allows local users to cause a denial of service (deadlock) via DIO requests.
The Linux kernel, before version 4.14.2, is vulnerable to a deadlock caused by fs/ocfs2/file.c:ocfs2_setattr(), as the function does not wait for DIO requests before locking the inode. This can be exploited by local users to cause a subsequent denial of service.
