Summary
Tilman Schmidt and Sasha Levin discovered a use-after-free condition in the
TTY implementation in the Linux kernel. A local attacker could use this to
expose sensitive information (kernel memory). (CVE-2015-8964)
It was discovered that the Video For Linux Two (v4l2) implementation in the
Linux kernel did not properly handle multiple planes when processing a
VIDIOC_DQBUF ioctl(). A local attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2016-4568)
CAI Qian discovered that shared bind mounts in a mount namespace
exponentially added entries without restriction to the Linux kernel's mount
table. A local attacker could use this to cause a denial of service (system
crash). (CVE-2016-6213)
It was discovered that the KVM implementation for x86/x86_64 in the Linux
kernel could dereference a null pointer. An attacker in a guest virtual
machine could use this to cause a denial of service (system crash) in the
KVM host. (CVE-2016-8630)
Eyal Itkin discovered that the IP over IEEE 1394 (FireWire) implementation
in the Linux kernel contained a buffer overflow when handling fragmented
packets. A remote attacker could use this to possibly execute arbitrary
code with administrative privileges. (CVE-2016-8633)
Marco Grassi discovered that the TCP implementation in the Linux kernel
mishandles socket buffer (skb) truncation. A local attacker could use this
to cause a denial of service (system crash). (CVE-2016-8645)
Andrey Konovalov discovered that the SCTP implementation in the Linux
kernel improperly handled validation of incoming data. A remote attacker
could use this to cause a denial of service (system crash). (CVE-2016-9555)
