A NULL pointer dereference flaw was found in the way the Linux kernel's networking implementation handled logging while processing certain invalid packets coming in via a VxLAN interface. A remote attacker could use this flaw to crash the system by sending a specially crafted packet to such an interface.

Description Prasad Pandit 2014-06-30 10:01:51 UTC 
Linux kernel built with the networking suppport(CONFIG_NET) is vulnerable to
a NULL pointer dereference flaw. It could occur while processing packets over
VxLAN interface of a virtual network.

An unprivileged user/process could use this flaw to crash the system kernel
resulting in DoS.

Comment 1 Prasad Pandit 2014-06-30 10:40:25 UTC 
Statement:

This issue does not affect the versions of the kernel package as shipped with Red Hat Enterprise Linux 5, 7 and Red Hat Enterprise MRG 2.

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