CVE-2016-9756

Published: 28 December 2016

arch/x86/kvm/emulate.c in the Linux kernel before 4.8.12 does not properly initialize Code Segment (CS) in certain error cases, which allows local users to obtain sensitive information from kernel stack memory via a crafted application.

From the Ubuntu security team

Dmitry Vyukov discovered that the KVM implementation in the Linux kernel did not properly initialize the Code Segment (CS) in certain error cases. A local attacker could use this to expose sensitive information (kernel memory).
