Lenovo issues firmware patches for over 100 laptop models

Lenovo has patched a trio of bugs reported by a researcher at ESET back in October, that could be abused to perform UEFI attacks, where malicious operations are loaded on a compromised device at an early stage of the boot process.

ESET said the vulnerabilities impact over 100 laptop models affecting millions of users worldwide and recommends that users patch their firmware immediately.
