GPU Rowhammer Attack Enables Privilege Escalation and Full System Compromise (infosecurity-magazine.com)

• GPUBreach uses GPU Rowhammer on GDDR6 to flip bits in page tables.
• Enables privilege escalation from user to root without physical access.
• Bypasses ECC on many GPUs; requires driver or hardware fixes.

"Researchers have demonstrated GPUBreach, a new attack using GPU Rowhammer on GDDR6 memory to flip bits and corrupt page tables, allowing an unprivileged process to escalate to system root privileges. The attack can be executed remotely via GPU commands without physical access, exploiting the lack of full ECC protection in many graphics cards."
