CVSS v3.1
Official Description
A buffer overflow has been identified in the SystemUserMasterHddPwdDxe driver in some Lenovo Notebook products which may allow an attacker with local access and elevated privileges to execute arbitrary code.
Technical Analysis
CVE-2023-4028 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires high 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 6.7.
