A researcher has discovered a zero-day firmware vulnerability that can be exploited by malicious hackers to disable security features on Lenovo, HP and likely other PCs.
Researcher Dmytro Oleksiuk revealed last week that he had identified a privilege escalation vulnerability in the Unified Extensible Firmware Interface (UEFI) present on all Lenovo ThinkPad series laptops. UEFI is the successor of the Basic Input/Output System (BIOS) firmware interface.
