kernel: privilege escalation

Package(s):kernel CVE #(s):CVE-2012-2136
Created:May 30, 2012 Updated:November 5, 2012
Description: From the Red Hat advisory:

It was found that the data_len parameter of the sock_alloc_send_pskb() function in the Linux kernel's networking implementation was not validated before use. A local user with access to a TUN/TAP virtual interface could use this flaw to crash the system or, potentially, escalate their privileges. Note that unprivileged users cannot access TUN/TAP devices until the root user grants them access.
