UEFI vulnerabilities

The hard disk password is stored in plaintext in a UEFI variable.

In UEFI firmware, lack of verified boot for certain firmware volumes (FV) may allow arbitrary code execution.

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.
