New GPUBreach Attack Enables Full CPU Privilege Escalation via GDDR6 Bit-Flips

Academic researchers have identified GPUBreach, a new series of RowHammer attacks targeting high-performance graphics processing units (GPPs) that enable privilege escalation to full host control. The research, encompassing GDDRHammer and GeForge techniques, demonstrates that attackers can exploit bit-flips in GDDR6 memory to bypass existing mitigations. GPUBreach advances beyond prior GPUHammer research by achieving CPU privilege escalation for the first time. Organizations utilizing high-performance GPUs in data centers or cloud environments face elevated risk. Mitigation requires hardware vendor updates, enhanced memory ECC protections, and continued development of RowHammer-resistant memory technologies.

New academic research has identified multiple RowHammer attacks against high-performance graphics processing units (GPUs) that could be exploited to escalate privileges and, in some cases, even take full control of a host. The efforts have been codenamed GPUBreach, GDDRHammer, and GeForge. GPUBreach goes a step further than GPUHammer, demonstrating for the first time that
