Ubuntu 15.10 : linux vulnerability (USN-3035-1)

high Nessus Plugin ID 92315

Language:

Synopsis

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

Description

Jan Stancek discovered that the Linux kernel's memory manager did not properly handle moving pages mapped by the asynchronous I/O (AIO) ring buffer to the other nodes. A local attacker could use this to cause a denial of service (system crash).

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.

Solution

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