Google published patches for over 70 software vulnerabilities in its Android security bulletin this month, finally fixing a security exploit for MediaTek chipsets said to have been in the wild for months, affecting millions of devices.
Google classifies CVE-2020-0069 as an elevation of privilege bug in MediaTek's command queue driver, and only gives it a high severity ranking in its bulletin.
The bug allows an attacker to get root access to an Android device without unlocking the bootloader, XDA-Developers said, by copying a script to their device and executing it in a shell.
The only critical flaws in the 2020-03-05 patch group were in closed source components from chip vendor Qualcomm, which accounted for 48 of the bugs in the Android bulletin overall.
A buffer overflow bug in Qualcomm's video processing is remotely exploitable, as is a Bluetooth bug.
