Mitchell Frank discovered that the Wi-Fi implementation in the Linux kernel when used as an access point would send IAPP location updates for stations before client authentication had completed. A physically proximate attacker could use this to cause a denial of service. 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.

This update provides the corresponding updates for the Linux kernel for Microsoft Azure Cloud systems for Ubuntu 14.04 ESM. 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.
e0a917b1318a227cbe7dcda44cca0d1aUbuntu Security Notice 4287-1 - 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. 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.
8ac6c9839149435e4e444efe50c60dbcUbuntu Security Notice 4285-1 - 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. It was discovered that the HSA Linux kernel driver for AMD GPU devices did not properly check for errors in certain situations, leading to a NULL pointer dereference. A local attacker could possibly use this to cause a denial of service. Various other issues were also addressed.

This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 18.04 LTS for Ubuntu 16.04 LTS. 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.
0eccdea34c52d8ecc3bb2dac5b1c9330Ubuntu Security Notice 4255-1 - 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. It was discovered that a race condition can lead to a use-after-free while destroying GEM contexts in the i915 driver for the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
