Package: linux-2.6
Version: 2.6.32-28
Severity: normal
Tags: patch

CVE-2010-3698 (denial of service by users with access to /dev/kvm) was
fixed upstream by commit 9581d442b9058d3699b4be568b6e5eae38a41493,
backported in stable update 2.6.32.26.

Unfortunately this causes an i386 qemu-kvm to crash on an amd64 kernel.
Romain Francoise says this is fixed by upstream commits:
