Preface: Arm was recently aware of reports of this vulnerability being exploited in the wild, but this exploit was a local attack. Perhaps, cybercriminals should help via email phishing or SMS functionality. Therefore, it attracted the attention of manufacturers.

Background: The Mali Bifrost architecture – implemented by the Mali-G3x, Mali-G5x, and Mali-G7x family of products, is the successor to the Midgard architecture and the predecessor of the Valhall architecture.

The Android and Linux version of the Mali GPUs Device Driver provide low-level access to the Mali GPUs that are part of the Bifrost family.

There are many ways to communicate with IPC, such as: Shared Memory, Message Queue, PIPE, FIFO, Unix Socket, etc. A process cannot access another process’s memory. However, the kernel has control over all processes and therefore can expose an interface that enables IPC. In Binder, this interface is the /dev/binder device, which is implemented by the Binder kernel driver.

Ref: A Mutex is a Mutually exclusive flag. It acts as a gate keeper to a section of code allowing one thread in and blocking access to all others.

Vulnerability details: Use After Free vulnerability in Arm Ltd Bifrost GPU Kernel Driver, Arm Ltd Valhall GPU Kernel Driver allows a local non-privileged user to make improper GPU memory processing operations to gain access to already freed memory.

This issue affects Bifrost GPU Kernel Driver: from r34p0 through r40p0; Valhall GPU Kernel Driver: from r34p0 through r40p0.
