CVE-2019-7222: Infoleak

First published: Sat Feb 02 2019(Updated: )

An information leakage issue was found in the way Linux kernel's KVM hypervisor handled page fault exception while emulating instructions like VMXON, VMCLEAR, VMPTRLD, VMWRITE with memory address as an operand. It occurs if the operand is an mmio address, as the returned exception object holds uninitialised stack memory contents. A guest user/process could use this flaw to leak host's stack memory contents to a guest. It affects only Intel processors and only when nested virtualization is enabled.
