Summary

The Arm Mali GPU kernel driver is vulnerable due to mishandled GPU memory operations, which allows unprivileged users to access freed memory. This issue affects multiple versions across the Bifrost, Valhall, and Midgard architectures, posing potential risks for system integrity and data security.

CISA Reported

CISA provides regional cyber and physical services to support security and resilience across the United States. CISA monitor the most dangerious vulnerabilities and have identifed as being exploited but is not known by the CISA to be used in ransomware campaigns. This is subject to change at pace

The CISA's recommendation is: Apply updates per vendor instructions.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
