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 From Kerin Millar 2008-10-03 11:31:10 0000 ------- 
The relevant patch is included in versions 2.6.25-r7 and 2.6.26-r2 of
hardened-sources.

------- Comment #2 From Kerin Millar 2009-07-20 20:08:02 0000 ------- 
hardened-kernel unaffected at present time. Removing alias.

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