gentoo-sources-2.6.26-r4 are based on 2.6.27.8.
Just marked stable on x86/amd64 by dsd.

Comment 3 Axel Dyks 2008-12-06 22:53:22 UTC

Argh! It's .26 not .27 sorry.

Daniel just added this patch to genpatches (Version 5) for 2.6.26

  http://sources.gentoo.org/viewcvs.py/linux-patches?rev=1424&view=rev

and has released 2.6.26-r4 (already stable on x86/amd64).

Does this mean the bug can be closed?

Amended the Status Whiteboard. hardened-kernel unaffected at present time. Removing alias.

PS: genpatches-2.6.27-7 added 2.6.27.8 and, as Axel pointed out, >=genpatches-2.6.26-5 is unaffected. =genpatches-2.6.25* remains vulnerable.
However, hardened-sources-2.6.25-r13 does not because we independently folded
in the same patch.
