Overview
Affected versions of this package are vulnerable to Heap-based Buffer Overflow in the ggml_nbytes function. An attacker can achieve memory corruption and potentially execute arbitrary code by supplying a specially crafted GGUF file with manipulated tensor dimensions that trigger an integer overflow, causing the function to return an insufficient buffer size.
