Millions Of Android Smartphones Running On Mali GPU Are Vulnerable To Attacks, And You Can’t Fix It

Google's Project Zero team has identified around five vulnerabilities affecting devices with Arm Mali GPUs.

Due to the slow and heavy patching process, millions of Android devices are vulnerable to cyberattacks. Research from Google’s Project Zero team has identified five vulnerabilities affecting devices with Arm Mali GPUs. You read that right, and this GPU is almost found on all Android devices from most smartphone manufacturers.

The researchers have categorized the vulnerabilities in CVE-2022-33917 and CVE-2022-36449. According to the report, the CVE-2022-33917 can allow attackers to control GPU processing to gain access to the free memory section. While the CVE-2022-36449 can enable attackers to access freed memory, disclose memory mappings details, and write outside of buffer bounds.

A vulnerability has been reported in Mali GPU drivers with the codenames Midgard, Bifrost, and Valhall. These GPUs are used in the following devices.
