kernel: gfs2: NULL pointer dereference in gfs2_evict_inode()

A NULL pointer dereference flaw was found in the gfs2 file system in the Linux kernel. This issue occurs on corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it has been freed and set to NULL. This flaw allows a privileged local user to cause ...
