In short
A flaw in Secure Boot allows attackers to bypass security protections designed to ensure only trusted code runs on system startup. This undermines the entire boot security mechanism that protects against malicious firmware and rootkits.
Technical detail
This vulnerability enables bypass of Secure Boot verification mechanisms through improper validation of signed code during the boot process. An attacker with physical access or firmware write permissions can leverage inadequate cryptographic verification (CWE-130) to load unsigned or maliciously signed code, compromising the integrity of the entire system stack.
