CWE-125Published: June 9, 2021· Updated: Jun 17, 2026
7.8
CVSS v3.1
Official Description
Out of bounds read in the firmware for some Intel(R) Processors may allow an authenticated user to potentially enable escalation of privilege via local access.
Technical Analysis
CVE-2020-12360 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
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 7.8.
