CVE-2017-18204
Published: 27 February 2018
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.
From the Ubuntu Security Team
It was discovered that a race condition existed in the OCFS2 file system implementation in the Linux kernel. A local attacker could use this to cause a denial of service (kernel deadlock).
