CVE-2022-36372

Privileged code execution via NVRAM-derived pointer write

Published Aug 11, 2023 · Updated Oct 9, 2024

Memory corruption in Intel NUC BIOS firmware allows local users with high privileges to execute arbitrary code during the PEI boot phase. The S3Resume2Pei module trusts the attacker-modifiable FPDT_Variable_NV value as a pointer, then writes resume statistics through a derived ACPI table address. High local privileges and an S3 sleep/resume cycle are required; code execution can influence later DXE and SMM boot stages.
