New GPUThor attack defeats NVIDIA ECC protection for root access

A newly disclosed Rowhammer attack called GPUThor can bypass error-correcting code (ECC) protections on NVIDIA GPUs, enabling denial-of-service (DoS) and root-level privilege escalation. The vulnerability affects NVIDIA graphics processing units, potentially allowing attackers to gain elevated access. Details on affected models and mitigation steps were not provided in the report.
