Ubuntu Security Notice 6256-1 - Jiasheng Jiang discovered that the HSA Linux kernel driver for AMD Radeon GPU devices did not properly validate memory allocation in certain situations, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service. Zheng Wang discovered that the Intel i915 graphics driver in the Linux kernel did not properly handle certain error conditions, leading to a double-free. A local attacker could possibly use this to cause a denial of service.
