Technical details
A memory leak in the MigTD virtio-serial driver fails to release allocated memory after its effective lifetime, allowing a privileged local attacker with Ring 0 access to trigger repeated allocations and exhaust system memory. The vulnerability requires local access and elevated privileges but no user interaction. The impact is limited to availability (denial of service) with no confidentiality or integrity impact.
