A cybersecurity company has discovered a security vulnerability affecting MediaTek's chips, which means roughly 40% of smartphones worldwide are affected. This includes several mobile devices Galaxy released in 2020 and later.
All modern MediaTek chips include an AI unit (APU) and a digital signal processor (DSP). After reverse-engineering DSP firmware, cybersecurity experts at Check Point Research discovered a vulnerability that, if exploited, allows attackers to hide malicious code and eavesdrop on user conversations.
There are several Samsung devices on the market with MediaTek chipsets, namely smartphones Galaxy A31, Galaxy A41, Galaxy A03S, Galaxy A12, Galaxy A22, Galaxy A32, Galaxy M22 and tablet Galaxy Tab A7 Lite. Fortunately for owners of the aforementioned devices, the Taiwanese chip giant is aware of this vulnerability and has even patched it, according to its October security bulletin. Samsung's new security patches do not mention this exploit, presumably for security reasons. In theory, however, this fix should be included in the Korean smartphone giant's October security patch. The one (and/or the November) series phones mentioned above Galaxy A a Galaxy M already received.
