Security researchers have discovered a new flaw in a MediaTek chip used in over a third of the world’s smartphones that could have potentially been used to listen in on private conversations. The chip in question is an audio processing chip by MediaTek that’s found in many Android smartphones from vendors such as Xiaomi, Oppo, Realme, and Vivo. Left unpatched, researchers say, a hacker could have exploited the vulnerabilities in the chip to eavesdrop on Android users and even hide malicious code.
