New Phoenix attack bypasses Rowhammer defenses in DDR5 memory
Academic researchers have devised a new variant of Rowhammer attacks that bypass the latest protection mechanisms on DDR5 memory chips from SK Hynix. A Rowhammer attack works by repeatedly accessing specific rows of memory cells at high-speed read/write operations to cause enough electrical interference to alter the value of the nearby bits from one to […]
NVIDIA shares guidance to defend GDDR6 GPUs against Rowhammer attacks
NVIDIA is warning users to activate System Level Error-Correcting Code mitigation to protect against Rowhammer attacks on graphical processors with GDDR6 memory. The company is reinforcing the recommendation as new research published by the University of Toronto demonstrates the practicallity of Rowhammer attacks against an NVIDIA A6000 GPU (graphical processing unit). “We ran GPUHammer on an NVIDIA RTX A6000 […]
