A serious hardware vulnerability, thought to be confined to UEFI drivers in Lenovo and HP laptops, has also been found in firmware running on motherboards sold by Gigabyte.
The flaw was publicly disclosed last week by researcher Dmytro Oleksiuk. No patches are yet available.
Oleksiuk said the flaw, which he calls ThinkPwn, is in the SystemSmmRuntimeRt UEFI driver, which he found on firmware in Lenovo ThinkPad laptops.
“Vulnerability is present in all of the ThinkPad series laptops, the oldest one that I have checked is X220 and the newest one is T450s (with latest firmware versions available at this moment),” Oleksiuk wrote on a Github entry. Oleksiuk published proof-of-concept exploit code for the vulnerability last week along with his disclosure.
