Acer has released a firmware update to address a security vulnerability that could be potentially weaponized to turn off UEFI Secure Boot on affected machines.
Tracked as CVE-2022-4020, the high-severity vulnerability affects five different models that consist of Aspire A315-22, A115-21, and A315-22G, and Extensa EX215-21 and EX215-21G.
The PC maker described the vulnerability as an issue that “may allow changes to Secure Boot settings by creating NVRAM variables.” Credited with discovering the flaw is ESET researcher Martin Smolár, who previously disclosed similar bugs in Lenovo computers.
