AI-suggested
An official patch is available and should be applied to affected linux-azure kernel versions. The vendor advisory confirms the issue is fixed. No additional mitigation is required beyond applying the update.
Description
A race condition vulnerability in the Linux kernel's KVM arm64 vgic subsystem was resolved. The flaw involved a use-after-free (UAF) condition triggered by concurrent interrupt affinity changes and LPI disabling, potentially leading to system compromise. The issue affects specific linux-azure kernel versions. A patch is available to address the race by taking proper references and adjusting interrupt migration handling.
