CVE-2011-3593

Publication date 15 December 2011

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.

From the Ubuntu Security Team

Gideon Naim discovered a flaw in the Linux kernel's handling VLAN 0 frames. An attacker on the local network could exploit this flaw to cause a denial of service.
