CVE-2010-2798 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-2798):
  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.
