CVE-2019-3016
Public on 2020-01-31

Description
A flaw was found in the way Linux kernel's KVM hypervisor handled deferred TLB flush requests from guest. A race condition may occur between the guest issuing a deferred TLB flush request to KVM, and then KVM handling and acknowledging it. This may result in invalid address translations from TLB being used to access guest memory, leading to a potential information leakage issue. An attacker may use this flaw to access guest memory locations that it should not have access to.
