Problem Description:

AMD and Intel CPUs support hardware virtualization using specialized data + structures that control various aspects of guest operation. These are the + Virtual Machine Control Structure (VMCS) on Intel CPUs, and the Virtual + Machine Control Block (VMCB) on AMD CPUs. Insufficient access controls allow + root users, including those running in a jail, to change these data + structures.

Impact:

An attacker with host root access (including to a jailed bhyve instance) can + use this vulnerability to achieve kernel code execution.
