Insecure Platform Key (PK) used in UEFI system firmware signature
Published Aug 26, 2024 · Updated Jun 28, 2026
A vulnerability exists in UEFI implementations that use a hard-coded software-based Platform Key (PK). An attacker in possession of the corresponding PK private key can sign arbitrary UEFI executables or firmware components, causing them to be trusted by affected systems and potentially bypassing UEFI Secure Boot trust validation.
