CWE-20Published: August 21, 2024· Updated: Jun 17, 2026
7.8
CVSS v3.1
Official Description
This SMM vulnerability affects certain modules, allowing privileged attackers to execute arbitrary code, manipulate stack memory, and leak information from SMRAM to kernel space, potentially leading to denial-of-service attacks.
Technical Analysis
CVE-2024-33657 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.
