AVID-2026-R0817

Description

Vulnerability CVE-2021-33430

Details

A Buffer Overflow vulnerability exists in NumPy 1.9.x in the PyArray_NewFromDescr_int function of ctors.c when specifying arrays of large dimensions (over 32) from Python code, which could let a malicious user cause a Denial of Service. NOTE: The vendor does not agree this is a vulneraility; In (very limited) circumstances a user may be able provoke the buffer overflow, the user is most likely already privileged to at least provoke denial of service by exhausting memory. Triggering this further requires the use of uncommon API (complicated structured dtypes), which is very unlikely to be available to an unprivileged user

Reason for inclusion in AVID: This CVE concerns a vulnerability in NumPy (a core dependency in AI stacks). It affects software used to build/train/run general-purpose AI systems and represents a security vulnerability (potential DoS) in a software supply-chain component. Public references (NVD entry, GitHub issue) provide sufficient signals for curation.
