**Name of the Vulnerable Software and Affected Versions** Xen (affected versions not specified) **Description** The issue is related to the construction of ACPI tables for PVH guests by the toolstack, which involves building the tables in local memory before copying them into guest memory. The excess space allocated in local memory is left with its prior contents, potentially leading to a data leak. This could allow an attacker to access confidential information. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
