Description Robert Buchholz (RETIRED) gentoo-dev 2008-09-12 13:22:16 UTC
CVE-2008-3525 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-3525):
  The sbni_ioctl function in drivers/net/wan/sbni.c in the wan
  subsystem in the Linux kernel 2.6.26.3 does not check for the
  CAP_NET_ADMIN capability before processing a (1) SIOCDEVRESINSTATS,
  (2) SIOCDEVSHWSTATE, (3) SIOCDEVENSLAVE, or (4) SIOCDEVEMANSIPATE
  ioctl request, which allows local users to bypass intended capability
  restrictions.
Comment 1 Kerin Millar 2008-10-03 11:31:10 UTC
The relevant patch is included in versions 2.6.25-r7 and 2.6.26-r2 of hardened-sources.
Comment 2 Kerin Millar 2009-07-20 20:08:02 UTC
hardened-kernel unaffected at present time. Removing alias.

PS: Anything using >=genpatches-2.6.25-6 is unaffected
