CVE-2022-33232

Hypervisor compromise via unchecked memory-test buffer copy

Published Feb 9, 2023 · Updated Aug 3, 2024

Memory corruption in Qualcomm Snapdragon Hypervisor firmware allows local users to compromise memory through large scattered-memory sharing tests. The Hypervisor test path copies input into a buffer without validating its size when memory-sharing tests use large, scattered regions. Local execution is required; successful corruption crosses the Hypervisor security boundary and compromises confidentiality, integrity, and availability.
