CVE-2022-3742
A potential vulnerability was discovered in LCFC BIOS for some Lenovo consumer notebook models that could allow a local attacker with elevated privileges to execute arbitrary code due to improper buffer validation.
Does this matter?
Lower severity and a low EPSS score (0.19%). Track it; it rarely justifies an emergency change on its own.
