DESCRIPTION

* CVE-2015-7550: Denial-of-service when reading and revoking a key concurrently.

A race condition in the cryptographic key management sub-system could lead
to a kernel crash when revoking and reading a key concurrently.  A local,
unprivileged user could use this flaw to cause a denial-of-service.


* CVE-2015-8543: Denial-of-service on out of range protocol for raw sockets.

It was discovered that a local user permitted to create raw sockets could
cause a denial-of-service by specifying an invalid protocol number for the
socket.


* Information leak in Bluetooth socket binding.

Lack of input validation when binding a Bluetooth socket could result in
kernel stack memory being leaked to userspace.  A local attacker could use
this flaw to gain information about the running kernel.
