kernel: kvm: Information leak within a KVM guest

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...

UBUNTU-CVE-2020-15852

An issue was discovered in the Linux kernel 5.5 through 5.7.9, as used in Xen through 4.13.x for x86 PV guests. An attacker may be granted the I/O port permissions of an unrelated task. This occurs because tssinvalidateiobitmap mishandling causes a loss of synchronization between the I/O bitmaps ...
