Assigned by
certcc

Description

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.

Public exploit

An exploit or proof of concept is public: anyone can try it against an unpatched system. CISA's SSVC rates its exploitation: a proof of concept is public.
