CWE-476  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 2.6.35 or higher.

Overview

Affected versions of this package are vulnerable to NULL Pointer Dereference. The gfs2_dirent_find_space function in fs/gfs2/dir.c in the Linux kernel before 2.6.35 uses an incorrect size value in calculations associated with sentinel directory entries, which allows local users to cause a denial of service (NULL pointer dereference and panic) and possibly have unspecified other impact by renaming a file in a GFS2 filesystem, related to the gfs2_rename function in fs/gfs2/ops_inode.c.
