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

Description A vulnerability in the Linux kernel has been resolved, related to the gfs2 file system. The issue involves checking the inode size of inline inodes to prevent on-disk corruption when reading inodes from disk. Specifically, the function gfs2 dinode in() now checks if the inode size is within the allowed range. Additionally, two checks in stuffed readpage() and gfs2 unstuffer page() that truncated inline data to the maximum allowed size have been removed as they were unnecessary.

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