CVE-2011-4594  (opens in a new tab)
CWE-476  (opens in a new tab)

How to fix?

Upgrade Centos:6 kernel-debug to version 0:2.6.32-220.7.1.el6 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debug package and not the kernel-debug package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

The __sys_sendmsg function in net/socket.c in the Linux kernel before 3.1 allows local users to cause a denial of service (system crash) via crafted use of the sendmmsg system call, leading to an incorrect pointer dereference.
