CVE-2022-3432
A potential vulnerability in a driver used during manufacturing process on the Ideapad Y700-14ISK that was mistakenly not deactivated may allow an attacker with elevated privileges to modify secure boot setting by modifying an NVRAM variable.
Does this matter?
Lower severity and a low EPSS score (0.29%). Track it; it rarely justifies an emergency change on its own.
