Vendor: Intel
Description
The vulnerability allows an attacker to bypass implemented security restrictions.
The vulnerability exists due to hardware debug modes and processor INIT setting allow to override of locks for some Intel Processors in Intel Boot Guard and Intel Trusted Execution Technology. An unauthenticated attacker with physical access to the system can bypass implemented security restrictions and escalate privileges on the system.
The vulnerability can be also exploited remotely by an authenticated attacker on the local network.
Mitigation
Install updates from vendor's website.
