Description Prasad Pandit 2013-09-25 12:05:55 UTC 
Linux kernel built with the IPv6 protocol(CONFIG_IPV6) support and an Ethernet
driver(ex. virtio-net) which has a UDP Fragmentation Offload(UFO) feature ON
is vulnerable to inadvertent memory corruptions and NULL pointer dereference 
flaw. It could occur while sending a large messages over an IPv6 connection. 
Though the crash occurs while sending messages, it could be triggered through a 
remote client by requesting larger data from a server.

A remote user user could use this flaw to crash the kernel, resulting in DoS. Despite the random nature of the memory corruptions, potential privilege escalation cannot be ruled out.

This issue does not affect the version of the kernel package as shipped with Red Hat Enterprise Linux 5.

This issue affects the versions of Linux kernel as shipped with Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG 2. Future kernel updates for Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG 2 may address this issue.
