Ubuntu Security Notice USN-6688-1

Ubuntu Security Notice 6688-1 - Pratyush Yadav discovered that the Xen network backend implementation in the Linux kernel did not properly handle zero length data request, leading to a null pointer dereference vulnerability. An attacker in a guest VM could possibly use this to cause a denial of service. It was discovered that the Habana’s AI Processors driver in the Linux kernel did not properly initialize certain data structures before passing them to user space. A local attacker could use this to expose sensitive information.
