Description Robert Buchholz (RETIRED) gentoo-dev 2008-09-11 17:41:12 UTC
CVE-2007-6716 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2007-6716):
  fs/direct-io.c in the dio subsystem in the Linux kernel before 2.6.23
  does not properly zero out the dio struct, which allows local users
  to cause a denial of service (OOPS), as demonstrated by a certain fio
  test.

hardened-kernel unaffected at present time (oldest version is based on 2.6.25). Removing alias.
