Ubuntu Security Notice 6635-1 - It was discovered that the USB subsystem in the Linux kernel contained a race condition while handling device descriptors in certain situations, leading to a out-of-bounds read vulnerability. A local attacker could possibly use this to cause a denial of service. Lucas Leong discovered that the netfilter subsystem in the Linux kernel did not properly validate some attributes passed from userspace. A local attacker could use this to cause a denial of service or possibly expose sensitive information.

Ubuntu Security Notice 6415-1 - Daniel Trujillo, Johannes Wikner, and Kaveh Razavi discovered that some AMD processors utilising speculative execution and branch prediction may allow unauthorised memory reads via a speculative side-channel attack. A local attacker could use this to expose sensitive information, including kernel memory. Ivan D Barrera, Christopher Bednarz, Mustafa Ismail, and Shiraz Saleem discovered that the InfiniBand RDMA driver in the Linux kernel did not properly check for zero-length STAG or MR registration. A remote attacker could possibly use this to execute arbitrary code.
