Technical details
This vulnerability is classified as a reliance on a component that is not updateable (CWE-1329) within the Windows Secure Boot architecture. An attacker with high privileges (Administrator) can exploit this flaw locally to bypass Secure Boot security features. Because the affected component cannot be updated through standard software patches, the vulnerability poses a persistent risk to the integrity of the boot process. Successful exploitation allows the attacker to circumvent protections intended to prevent the execution of untrusted bootloaders or firmware.
