CVE-2021-44879

Published: 14 February 2022

In gc_data_segment in fs/f2fs/gc.c in the Linux kernel before 5.16.3, special files are not considered, leading to a move_data_page NULL pointer dereference.

From the Ubuntu security team

Wenqing Liu discovered that the f2fs file system implementation in the Linux kernel did not properly validate inode types while performing garbage collection. An attacker could use this to construct a malicious f2fs image that, when mounted and operated on, could cause a denial of service (system crash).
