Details

Ben Hawkes discovered that the Linux netfilter implementation did not
correctly perform validation when handling IPT_SO_SET_REPLACE events. A
local unprivileged attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code with administrative
privileges. (CVE-2016-3134)

Ben Hawkes discovered an integer overflow in the Linux netfilter
implementation. On systems running 32 bit kernels, a local unprivileged
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code with administrative privileges.
(CVE-2016-3135)

Ralf Spenneberg discovered that the USB driver for Clie devices in the
Linux kernel did not properly validate the endpoints reported by the
device. An attacker with physical access could cause a denial of service
(system crash). (CVE-2015-7566)

It was discovered that a race condition existed when handling heartbeat-
timeout events in the SCTP implementation of the Linux kernel. A remote
attacker could use this to cause a denial of service. (CVE-2015-8767)

It was discovered that a race condition existed in the ioctl handler for
the TTY driver in the Linux kernel. A local attacker could use this to
cause a denial of service (system crash) or expose sensitive information.
(CVE-2016-0723)

Andrey Konovalov discovered that the ALSA USB MIDI driver incorrectly
performed a double-free. A local attacker with physical access could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code with administrative privileges. (CVE-2016-2384)

Dmitry Vyukov discovered that the Advanced Linux Sound Architecture (ALSA)
framework did not verify that a FIFO was attached to a client before
attempting to clear it. A local attacker could use this to cause a denial
of service (system crash). (CVE-2016-2543)

Dmitry Vyukov discovered that a race condition existed in the Advanced
Linux Sound Architecture (ALSA) framework between timer setup and closing
of the client, resulting in a use-after-free. A local attacker could use
this to cause a denial of service. (CVE-2016-2544)

Dmitry Vyukov discovered a race condition in the timer handling
implementation of the Advanced Linux Sound Architecture (ALSA) framework,
resulting in a use-after-free. A local attacker could use this to cause a
denial of service (system crash). (CVE-2016-2545)

Dmitry Vyukov discovered race conditions in the Advanced Linux Sound
Architecture (ALSA) framework’s timer ioctls leading to a use-after-free. A
local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2016-2546)

Dmitry Vyukov discovered that the Advanced Linux Sound Architecture (ALSA)
framework’s handling of high resolution timers did not properly manage its
data structures. A local attacker could use this to cause a denial of
service (system hang or crash) or possibly execute arbitrary code.
(CVE-2016-2547, CVE-2016-2548)

Dmitry Vyukov discovered that the Advanced Linux Sound Architecture (ALSA)
framework’s handling of high resolution timers could lead to a deadlock
condition. A local attacker could use this to cause a denial of service
(system hang). (CVE-2016-2549)

Ralf Spenneberg discovered that the USB driver for Treo devices in the
Linux kernel did not properly validate the endpoints reported by the
device. An attacker with physical access could cause a denial of service
(system crash). (CVE-2016-2782)
