Name of the Vulnerable Software and Affected Versions Intel(R) processors (affected versions not specified)

Description The issue is related to the activation of test or debug logic at runtime for some Intel(R) processors, which may allow an unauthenticated user to potentially enable escalation of privilege via physical access. This is due to insufficient protection of service data in the BIOS/UEFI firmware. Exploitation of the issue may allow an attacker to gain elevated privileges and access sensitive information. The problem is also associated with a debugging functionality that has excessive privileges, potentially allowing attackers to read encrypted files.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
