A new GPU-based Rowhammer attack capable of escalating privileges to a full system compromise has been demonstrated by researchers at the University of Toronto.<\/p>\n

The technique, called GPUBreach by researchers at the University of Toronto, shows how memory corruption on modern graphics hardware can be leveraged to gain root-level access across both GPU and CPU environments.<\/p>\n

The research, set to be presented at the 47th IEEE Symposium on Security & Privacy in 2026, builds on earlier work that identified bit flips in GPU memory but did not achieve targeted control or escalation.<\/p>\n

Exploiting GPU Memory For Privilege Escalation<\/strong><\/h2>\n

A technical blog post<\/a> published by the researchers explained that GPUBreach focuses on corrupting GPU page tables, which are responsible for managing memory access on the device.<\/p>\n

By using Rowhammer-induced bit flips in GDDR6 memory, the researchers demonstrated that an unprivileged CUDA kernel can gain arbitrary read and write access to GPU memory.<\/p>\n

This access enables further exploitation. By targeting memory-safety vulnerabilities in the NVIDIA driver, the attack can extend beyond the GPU and compromise CPU memory.<\/p>\n

The end result is full system control, including the ability to spawn a root shell, even when widely recommended protections such as the input-output memory management unit (IOMMU) remain enabled.<\/p>\n

Impact and Security Implications<\/strong><\/h2>\n

The study outlines several consequences of the attack across different workloads:<\/p>\n

    \n
  • \n

    Arbitrary GPU memory access, including cross-process data exposure<\/p>\n<\/li>\n

  • \n

    Leakage of cryptographic keys during GPU-based operations<\/p>\n<\/li>\n

  • \n

    Manipulation of machine learning processes, reducing accuracy from 80% to 0%<\/p>\n<\/li>\n

  • \n

    Escalation to CPU-level privileges, resulting in full system compromise<\/p>\n<\/li>\n<\/ul>\n

    The researchers also showed that sensitive data stored in GPU memory, including large language model (LLM) weights, could be extracted under certain conditions.<\/p>\n

    The findings challenge existing assumptions around GPU security. While mechanisms such as error-correcting code memory can mitigate some forms of bit corruption, they are not foolproof. In cases involving multiple bit flips, errors may go undetected, leaving systems exposed.<\/p>\n

    As GPUs continue to play a central role in high-performance computing, artificial intelligence and cryptographic operations, the research suggests that current defensive measures may require significant reassessment.<\/p>\n","protected":false},"excerpt":{"rendered":"
