CVSS v3.1
Official Description
A buffer overflow in the SystemBootManagerDxe driver in some Lenovo Notebook products may allow an attacker with local privileges to execute arbitrary code.
Technical Analysis
CVE-2022-1892 requires local access, meaning attackers must already have a foothold on the target system.
