[USN-2807-1] Linux kernel (Wily HWE) vulnerability

Severity High
Affected Packages 8
CVEs 1
Info Packages Vulnerabilities

The system could be made to crash under certain conditions.

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.
