Name of the Vulnerable Software and Affected Versions Arm versions (affected versions not specified)

Description The issue concerns unbounded memory consumption for 2nd-level page tables. Certain actions, such as removing pages from a guest's P2M (Physical-to-Machine) mapping, may incur memory allocations from the global memory pool when large pages are used to map guest pages in the 2nd-stage page tables. A malicious guest could potentially exhaust the global memory pool by manipulating its own P2M mappings.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
