Ubuntu Security Notice 4485-1 - Timothy Michaud discovered that the i915 graphics driver in the Linux kernel did not properly validate user memory locations for the i915_gem_execbuffer2_ioctl. A local attacker could possibly use this to cause a denial of service or execute arbitrary code. It was discovered that the Kvaser CAN/USB driver in the Linux kernel did not properly initialize memory in certain situations. A local attacker could possibly use this to expose sensitive information. Various other issues were also addressed.

Ubuntu Security Notice 4483-1 - Chuhong Yuan discovered that go7007 USB audio device driver in the Linux kernel did not properly deallocate memory in some failure conditions. A physically proximate attacker could use this to cause a denial of service. Fan Yang discovered that the mremap implementation in the Linux kernel did not properly handle DAX Huge Pages. A local attacker with access to DAX storage could use this to gain administrative privileges. Various other issues were also addressed.

Ubuntu Security Notice 4440-1 - It was discovered that the network block device implementation in the Linux kernel did not properly check for error conditions in some situations. An attacker could possibly use this to cause a denial of service. It was discovered that the kernel->user space relay implementation in the Linux kernel did not properly check return values in some situations. A local attacker could possibly use this to cause a denial of service. Various other issues were also addressed.

Ubuntu Security Notice 4439-1 - It was discovered that the network block device implementation in the Linux kernel did not properly check for error conditions in some situations. An attacker could possibly use this to cause a denial of service. It was discovered that the btrfs file system implementation in the Linux kernel did not properly validate file system metadata in some situations. An attacker could use this to construct a malicious btrfs image that, when mounted, could cause a denial of service. Various other issues were also addressed.
