USN-5062-1: Linux kernel vulnerability

Maxim Levitsky discovered that the KVM hypervisor implementation for AMD processors in the Linux kernel did not properly prevent a guest VM from enabling AVIC in nested guest VMs. An attacker in a guest VM could use this to write to portions of the host's physical memory...

CVE-2021-28695

CVE-2021-28695 affects the Xen hypervisor (IOMMU page mapping) on AMD systems. The issue arises when firmware specifies discontinuous memory ranges that are identity-mapped during translation, allowing a guest to retain access to memory ranges it should not access after device de-assignment. Docu...
