Descriptions
The KVM implementation in the Linux kernel through 4.20.5 has an Information Leak.
La implementación KVM en el kernel de Linux, hasta la versión 4.20.5, tiene una fuga de información.
An information leakage issue was found in the way Linux kernel's KVM hypervisor handled page fault exceptions while emulating instructions like VMXON, VMCLEAR, VMPTRLD, and VMWRITE with memory address as an operand. It occurs if the operand is a mmio address, as the returned exception object holds uninitialized stack memory contents. A guest user/process could use this flaw to leak host's stack memory contents to a guest.
KVM suffers from an uninitialized memory leak vulnerability in kvm_inject_page_fault.
