{"data":{"id":"24c95f24-f80a-420d-b357-c6ba51118b8a","title":"GPUThor hardware attack can root Nvidia GPU systems","summary":"Researchers from the University of Toronto developed GPUThor, a new Rowhammer attack (a technique that exploits how tightly packed memory cells can leak electrical charge to flip stored bits) that can defeat error-correcting codes (ECC, a defense that detects and fixes memory errors) on Nvidia GPUs and gain root access (complete control) to the system. Unlike previous GPU attacks, GPUThor uses non-uniform row hammering to create multiple bit flips simultaneously, which the ECC system cannot handle, and works much faster than earlier methods.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://www.csoonline.com/article/4215392/gputhor-hardware-attack-can-root-nvidia-gpu-systems.html","publishedAt":"2026-08-28T18:46:28.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"high","attackType":["other"],"issueType":"news","affectedPackages":null,"affectedVendors":["NVIDIA"],"affectedVendorsRaw":["Nvidia"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"patchAvailable":null,"disclosureDate":"2026-08-28T18:46:28.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"inference","llmSpecific":false,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null}}
