CVE-2014-7841: Null Pointer Dereference

First published: Wed Nov 12 2014(Updated: )

An SCTP server doing ASCONF will panic on malformed INIT ping-of-death in the form of: ------------ INIT[PARAM: SET_PRIMARY_IP] ------------&gt; A remote attacker could use this flaw to crash the system by sending a maliciously prepared SCTP packet in order to trigger a NULL pointer dereference on the server. Upstream patch: <a href="https://git.kernel.org/cgit/linux/kernel/git/davem/net.git/commit/?id=e40607cbe270a9e8360907cb1e62ddf0736e4864">https://git.kernel.org/cgit/linux/kernel/git/davem/net.git/commit/?id=e40607cbe270a9e8360907cb1e62ddf0736e4864</a> Acknowledgements: This issue was discovered by Liu Wei of Red Hat.
