Host privilege escalation via mishandled memory objects
Published Apr 15, 2020 · Updated Aug 4, 2024
Hyper-V elevation of privilege in affected Microsoft Windows releases lets guest OS users gain host privileges via crafted memory objects. The Hyper-V host mishandles in-memory objects supplied across the virtualization boundary; Microsoft has not disclosed the affected function or specific memory-safety error. Exploitation requires adjacent access and existing high privileges, and the reported consequence is privilege elevation on the Hyper-V host.
