DESCRIPTION

* CVE-2016-9793: Denial-of-service in socket configuration.

Incorrect validation of arguments for the setsockopt ioctl could allow
a local user with CAP_NET_ADMIN privileges to cause memory corruption
or crash the kernel.


* CVE-2016-9806: Use after free in netlink dump interface.

Incorrect locking in the generic netlink interface can cause a use after
free and kernel panic when attempting to dump multiple interfaces
concurrently.


* CVE-2016-9794: Denial-of-service when playing audio stream.

A missing lock when computing elapsed period of the playing stream
could lead to a use-after-free if the stream is released in a concurrent
thread. An attacker could use this flaw to cause a denial-of-service.


* CVE-2016-9756: Information leak in KVM x86 emulator.

Failure to initialize memory in generic x86 emulator resulted in leaking
of kernel stack into userspace. An attacker can use this vulnerability
to introspect kernel memory.
