CVE-2017-2584

Published: 14 January 2017

arch/x86/kvm/emulate.c in the Linux kernel through 4.9.3 allows local users to obtain sensitive information from kernel memory or cause a denial of service (use-after-free) via a crafted application that leverages instruction emulation for fxrstor, fxsave, sgdt, and sidt.

From the Ubuntu security team

Dmitry Vyukov discovered that the KVM implementation in the Linux kernel improperly emulated certain instructions. A local attacker could use this to obtain sensitive information (kernel memory).
