Platform sample code firmware in 4th Generation Intel Core Processor, 5th Generation Intel Core Processor, 6th Generation Intel Core Processor, 7th Generation Intel Core Processor and 8th Generation Intel Core Processor contains a logic error which may allow physical attacker to potentially bypass firmware authentication.
Weakness
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
