libxl leaks data to PVH guests via ACPI tables

Published Dec 19, 2024

Modified 1 years ago

Details

PVH guests have their ACPI tables constructed by the toolstack. The construction involves building the tables in local memory, which are then copied into guest memory. While actually used parts of the local memory are filled in correctly, excess space that is being allocated is left with its prior contents.
