Such manipulation of the argument g_idx leads to out-of-bounds read. The attack can be executed remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 7.3.0 is able to resolve this issue. The name of the patch is 877c732f7d7dccd56a729844c6a5bd20f3aa8bb1. Upgrading the affected component is recommended.
A vulnerability allowing for an out-of-bounds read has been identified in ModelCloud GPTQModel versions prior to 7.2.0. This issue arises in the Triton dequantization kernel, specifically within the 'gptqmodel/nn_modules/qlinear/tritonv2.py' file. The vulnerability is triggered by an unchecked 'g_idx' argument, which can be manipulated to read beyond the intended memory bounds. This flaw can be exploited remotely, potentially leading to a crash or disclosure of adjacent memory. The issue has been publicly disclosed and can be exploited by loading a crafted GPTQ checkpoint into the model.
Users can upgrade to ModelCloud GPTQModel version 7.3.0 or later, where this vulnerability has been fixed.
