CVE-2026-110695 Details
Description
A vulnerability was detected in turboderp ExLlamaV2 up to 0.3.2. Affected is the function STFile.get_tensor of the file exllamav2/stloader.py of the component Safetensors Tensor Loader. Performing a manipulation of the argument data_offsets results in buffer overflow. The attack is possible to be carried out remotely. The exploit is now public and may be used. The project was informed of the problem early through an issue report but has not responded yet.
A heap-based buffer overflow vulnerability has been identified in Turboderp ExLlamaV2 versions through 0.3.2. The issue arises in the Safetensors Tensor Loader component, specifically within the STFile.get_tensor function of the exllamav2/stloader.py file. The vulnerability allows for remote exploitation by manipulating the data_offsets argument, leading to a buffer overflow condition. Despite being reported to the project, no response has been received.
Users are advised to validate the Safetensors header before reading, ensuring that 'data_offsets' are non-negative, contiguous, and accurately reflect the tensor's shape and data size. Until a fixed release is available, it is recommended to only load models from trusted sources and to use the reference Safetensors library for parsing.
