Description

A flaw was found in the Linux kernel's Kernel-based Virtual Machine (KVM) component. This vulnerability occurs when a virtual machine is shutting down, and KVM attempts to mark memory as dirty without an active virtual CPU. This can lead to a memory leak, impacting system stability and resource availability. The issue is related to how KVM handles guest memory during the destruction of a virtual CPU.
