CVE-2016-8630 (retired)

Priority
Description
The x86_decode_insn function in arch/x86/kvm/emulate.c in the Linux kernel
before 4.8.7, when KVM is enabled, allows local users to cause a denial of
service (host OS crash) via a certain use of a ModR/M byte in an undefined
instruction.
Ubuntu-Description
It was discovered that the KVM implementation for x86/x86_64 in the Linux
kernel could dereference a null pointer. An attacker in a guest virtual
machine could use this to cause a denial of service (system crash) in the
KVM host.
