Description Stefan Behte (RETIRED) gentoo-dev Security 2008-11-11 00:25:38 UTC
CVE-2008-5029 (
  The __scm_destroy function in net/core/scm.c in the Linux kernel, 2.6.26, and earlier makes indirect recursive calls to
  itself through calls to the fput function, which allows local users
  to cause a denial of service (panic) via vectors related to sending
  an SCM_RIGHTS message through a UNIX domain socket and closing file

Populated Status Whiteboard. Here's the upstream patch:;a=commit;h=f8d570a4

Should this patch be applied independently, it is also strongly recommended to apply this related patch:

"scm: fix scm_fp_list->list initialization made in wrong place";a=commitdiff;h=5421ae0153b4ba0469967cfd8de96144e3bf3979

hardened-kernel unaffected at present time. Removing alias.

PS: genpatches-2.6.26-4 added genpatches-2.6.27-5 added =genpatches-2.6.25* remains vulnerable. However, hardened-sources-2.6.25-r13 does not because we independently folded in the newest stable patches.
