Ubuntu 15.10 : linux vulnerability (USN-2803-1)

medium Nessus Plugin ID 86813


The remote Ubuntu host is missing one or more security-related patches.


Ben Serebrin discovered that the KVM hypervisor implementation in the Linux kernel did not properly catch Alignment Check exceptions. An attacker in a guest virtual machine could use this to cause a denial of service (system crash) in the host OS.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected linux-image-4.2-generic, linux-image-4.2-generic-lpae and / or linux-image-4.2-lowlatency packages.
