Description

A flaw was found in the Linux kernel's Kernel-based Virtual Machine (KVM) for ARM64, specifically within the vgic-its component. This vulnerability occurs when multiple concurrent operations incorrectly drop the translation cache's reference to an entry more than once during cache invalidation. This leads to a use-after-free condition, which can result in memory corruption. The primary impact is potential system instability or a denial of service.
