A local attacker could use this to expose sensitive information. It was discovered that the Atheros 802.11ac wireless USB device driver in the Linux kernel did not properly validate device metadata. A physically proximate attacker could use this to cause a denial of service. Various other issues were also addressed.
b323d62bf07d96f4f3d2166c1ad9acd4fdbed940dc5f567a0bc7c6cdf973768dIt was discovered that the binder IPC implementation in the Linux kernel did not properly perform bounds checking in some situations, leading to an out-of-bounds write. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. It was discovered that the Linux kernel did not properly clear data structures on context switches for certain Intel graphics processors. A local attacker could use this to expose sensitive information. Various other issues were also addressed.

A physically proximate attacker could use this to cause a denial of service. It was discovered that a race condition existed in the Virtual Video Test Driver in the Linux kernel. An attacker with write access to /dev/video0 on a system with the vivid module loaded could possibly use this to gain administrative privileges. Various other issues were also addressed.
