[USN-3256-2] Linux kernel (HWE) vulnerability

Severity High
Affected Packages 12
CVEs 1
Info Packages Vulnerabilities

The system could be made to crash under certain conditions.

USN-3256-1 fixed vulnerabilities in the Linux kernel for Ubuntu
14.04 LTS, Ubuntu 16.04 LTS, and Ubuntu 16.10. This update provides
the corresponding updates for the Linux Hardware Enablement (HWE)
kernel for each of the respective prior Ubuntu LTS releases.

Andrey Konovalov discovered that the AF_PACKET implementation in the Linux
kernel did not properly validate certain block-size data. A local attacker
could use this to cause a denial of service (system crash).
