Description Prasad Pandit 2014-07-24 13:57:24 UTC 
Linux kernel built with the support for Stream Control Transmission Protocol
(CONFIG_IP_SCTP) is vulnerable to a NULL pointer dereference flaw. It could
occur when simultaneous new connections are initiated between the same pair of
hosts.

A remote user/program could use this flaw to crash the system kernel resulting
in DoS.

Comment 12 Petr Matousek 2014-09-05 08:41:05 UTC 
Statement:

This issue does not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux 5 as it doesn't provide support for AUTH chunks.

This issue affects the versions of the Linux kernel as shipped with Red Hat Enterprise Linux 6 and 7. Future kernel updates for Red Hat Enterprise Linux 6 and 7 may address this issue. This issue has been fixed in Red Hat Enterprise MRG via RHSA-2014:1083.
