5.9
CVSS v3.1
Official Description
In some Lenovo IdeaPad consumer notebook models, a race condition in the BIOS flash device locking mechanism is not adequately protected against, potentially allowing an attacker with administrator access to alter the contents of BIOS.
Technical Analysis
CVE-2018-9069 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 5.9.
