Official Description
Insufficient control flow management in the firmware for some Intel(R) Processors may allow an unauthenticated user to potentially enable escalation of privilege via physical access.
Technical Analysis
CVE-2020-12359 requires local access, meaning attackers must already have a foothold on the target system.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 6.8.
