Ubuntu Security Notice USN-5535-1

Ubuntu Security Notice 5535-1 - Joseph Nuzman discovered that some Intel processors did not properly initialise shared resources. A local attacker could use this to obtain sensitive information. Mark Ermolov, Dmitry Sklyarov and Maxim Goryachy discovered that some Intel processors did not prevent test and debug logic from being activated at runtime. A local attacker could use this to escalate privileges.

Ubuntu Security Notice USN-5529-1

Ubuntu Security Notice 5529-1 - It was discovered that the Atheros ath9k wireless device driver in the Linux kernel did not properly handle some error conditions, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Yongkang Jia discovered that the KVM hypervisor implementation in the Linux kernel did not properly handle guest TLB mapping invalidation requests in some situations. An attacker in a guest VM could use this to cause a denial of service in the host OS.
