Official Description
Insufficient memory write check in SMM service for EDK II may allow an authenticated user to potentially enable escalation of privilege, information disclosure and/or denial of service via local access.
Technical Analysis
CVE-2018-12182 requires local access, meaning attackers must already have a foothold on the target system.
