Positive Technologies (AI Summary)

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the f2fs filesystem within the Linux kernel related to handling read-only conditions during remount operations with multi-device images. Specifically, an incorrect check for read-only status can lead to a kernel panic when updating a multi-device image where one of the secondary devices is set to read-only. This occurs when attempting to remount the filesystem with read-write permissions after an initial read-only mount. The issue is triggered by an inconsistent mount status and manifests as a kernel BUG at fs/f2fs/inline.c. The f2fs dev is readonly() function was introduced to address this issue by correctly checking the read-write status of multiple devices during the f2fs remount() operation.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
