XSA-299 addressed critical issues in restartable PV type change operations, but some corner cases were missed, allowing a malicious PV guest admin to escalate privilege to the host. Vulnerable systems include all security-supported Xen versions for x86, excluding Arm systems. Timing for attacks is challenging.
