[USN-3106-2] Linux kernel (Xenial HWE) vulnerability

Severity High
Affected Packages 8
CVEs 1
Info Packages Vulnerabilities

The system could be made to run programs as an administrator.

USN-3106-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04
LTS. This update provides the corresponding updates for the Linux
Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu
14.04 LTS.

It was discovered that a race condition existed in the memory manager of
the Linux kernel when handling copy-on-write breakage of private read-only
memory mappings. A local attacker could use this to gain administrative
privileges.
