DESCRIPTION

* CVE-2015-1333: Denial-of-service in the keyring subsystem.

A flaw in the keyring subsystem leads to a memory leak when repeatedly
adding the same key to kernel via the add_key() syscall.  A local,
unprivileged user could use this flaw to exhaust the memory on the system
and cause a denial-of-service.


* CVE-2015-3212: Denial-of-service when processing SCTP ASCONF packets.

Incorrect locking in the SCTP subsystem can trigger memory corruption
and a kernel panic when processing ASCONF packets.
