Description Alex Legler (RETIRED) archtester gentoo-dev Security 2009-10-20 21:55:04 UTC 
CVE-2009-2910 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-2910):
  arch/x86/ia32/ia32entry.S in the Linux kernel before 2.6.31.4 on the
  x86_64 platform does not clear certain kernel registers before a
  return to user mode, which allows local users to read register values
  from an earlier process by switching an ia32 process to 64-bit mode.
