CVE-2022-22063Public exploit

Hypervisor takeover via unprotected boot remapper

Published Dec 14, 2022 · Updated Apr 18, 2025

Memory corruption in Qualcomm Snapdragon hypervisor firmware allows local users to read and write protected EL2 memory through the boot remapper. The hypervisor leaves the non-secure APCS_BOOT_START_ADDR_NSEC register and remapped window accessible from EL1, bypassing stage 2 translation. Exploitation requires a modified or compromised operating-system kernel and can replace hypervisor code, break virtual-machine isolation, or interrupt the device.
