CVE-2018-13096

Published: 3 July 2018

An issue was discovered in fs/f2fs/super.c in the Linux kernel through 4.14. A denial of service (out-of-bounds memory access and BUG) can occur upon encountering an abnormal bitmap size when mounting a crafted f2fs image.

From the Ubuntu security team

Wen Xu discovered that the f2fs file system implementation in the Linux kernel did not properly validate metadata. An attacker could use this to construct a malicious f2fs image that, when mounted, could cause a denial of service (system crash).
