CVE-2011-3593
Description
From CVE.org
A certain Red Hat patch to the vlan_hwaccel_do_receive function in net/8021q/vlan_core.c in the Linux kernel 2.6.32 on Red Hat Enterprise Linux (RHEL) 6 allows remote attackers to cause a denial of service (system crash) via priority-tagged VLAN frames.
Statement
This issue did not affect the Linux kernels as shipped with Red Hat Enterprise Linux 4, 5, and Red Hat Enterprise MRG. It affects the Linux kernel as shipped with Red Hat Enterprise Linux 6 due to incorrect backporting of upstream patches. A future kernel update in Red Hat Enterprise Linux 6 may address this issue.
