CVE-2023-33036

Permanent hypervisor denial of service via PSCI call

Published Jan 2, 2024 · Updated Sep 6, 2024

NULL pointer dereference in Qualcomm Snapdragon Hypervisor allows guest OS users to permanently interrupt availability via a PSCI call. The PSCI-call path fails to reject a call from an untrusted VM that lacks PSCI support before dereferencing a null pointer; Qualcomm has not named the affected function. An attacker must control code in such a guest VM, and the documented consequence is persistent hypervisor failure with no reported data access or modification.
