CVE-2008-2137 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-2137):
  The (1) sparc_mmap_check function in arch/sparc/kernel/sys_sparc.c and the
  (2) sparc64_mmap_check function in arch/sparc64/kernel/sys_sparc.c, in the
  Linux kernel before 2.6.25.3, omit some virtual-address range (aka span)
  checks when the mmap MAP_FIXED bit is not set, which allows local users to
  cause a denial of service (panic) via unspecified mmap calls.

hardened-kernel unaffected at present time. Removing alias.

PS: Anything using >=genpatches-2.6.25-4 is unaffected
