GPUBreach Attack: New CPU Privilege Escalation Vulnerability in GPUs

A new academic research has uncovered a series of RowHammer attacks against high-performance graphics processing units (GPUs), which could be exploited to escalate privileges and potentially gain full control of a host system.

The attacks, codenamed GPUBreach, GDDRHammer, and GeForge, have been found to affect GPUs that use GDDR6 memory, making them vulnerable to bit-flip attacks that can be used to gain elevated privileges.

GPUBreach is a significant discovery, as it demonstrates for the first time that RowHammer attacks can be used to escalate privileges from the GPU to the CPU, potentially allowing attackers to take full control of a system.

The research highlights the importance of securing GPUs, which are increasingly being used in a wide range of applications, from gaming to artificial intelligence and machine learning.

The GPUBreach attack is a reminder that the security of GPUs is just as important as the security of CPUs, and that vulnerabilities in GPUs can have serious consequences if left unaddressed.
