CVSS v3.1
Official Description
A buffer overflow was reported in the SmiFlash module in some Lenovo Desktop products that may allow a local attacker with elevated privileges to execute arbitrary code.
Technical Analysis
CVE-2023-43578 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.
