    CVE-2026-116502 (GCVE-0-2026-116502)

    Vulnerability from nvd – Published: 2026-10-26 20:15 – Updated: 2026-10-26 20:15
    VLAI
    Title
    turboderp-org ExLlamaV2 GPTQ Index q_matrix.cu make_sequential out-of-bounds write
    Summary
    A flaw has been found in turboderp-org ExLlamaV2 up to 0.3.2. The impacted element is the function QMatrix::make_sequential of the file exllamav2/exllamav2_ext/cuda/q_matrix.cu of the component GPTQ Index Handler. Executing a manipulation of the argument g_idx can lead to out-of-bounds write. The attack needs to be launched locally. The project was informed of the problem early through an issue report but has not responded yet.

    CVE-2026-84286 (GCVE-0-2026-84286)

    Vulnerability from nvd – Published: 2026-10-12 17:01 – Updated: 2026-10-19 11:04
    VLAI
    Title
    OOB Read/Write via Negative Array Index in exllamav3_ext Kernel Table
    Summary
    ExLlamaV3’s EXL3 loader uses an untrusted, model-supplied index to select a CUDA kernel without first verifying that the index is within bounds. A malicious model can force the code to read and invoke an out‑of‑range function pointer, resulting in a reproducible crash. Under specific conditions involving certain host memory layouts, it may be possible for an attacker to exploit this vulnerability to achieve controlled indirect kernel dispatch during model load.

The impacted element is the function QMatrix::make_sequential of the file exllamav2/exllamav2_ext/cuda/q_matrix.cu of the component GPTQ Index Handler. Executing a manipulation of the argument g_idx can lead to out-of-bounds write. The attack needs to be launched locally. The project was informed of the problem early through an issue report but has not responded yet.

    CVE-2026-84286 (GCVE-0-2026-84286)

    Vulnerability from cvelistv5 – Published: 2026-10-12 17:01 – Updated: 2026-10-19 11:04
    VLAI
    Title
    OOB Read/Write via Negative Array Index in exllamav3_ext Kernel Table
    Summary
    ExLlamaV3’s EXL3 loader uses an untrusted, model-supplied index to select a CUDA kernel without first verifying that the index is within bounds. A malicious model can force the code to read and invoke an out‑of‑range function pointer, resulting in a reproducible crash. Under specific conditions involving certain host memory layouts, it may be possible for an attacker to exploit this vulnerability to achieve controlled indirect kernel dispatch during model load.
