Ubuntu 14.04 LTS : Linux kernel (Wily HWE) vulnerability (USN-3035-3)

high Nessus Plugin ID 92317

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-3035-3 advisory.

 USN-3035-1 fixed vulnerabilities in the Linux kernel for Ubuntu 15.10. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 15.10 for Ubuntu 14.04 LTS.

 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).

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
