## Overview

PyTorch before v2.2.0 was discovered to contain a heap buffer overflow vulnerability in the component /runtime/vararg_functions.cpp. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted input.

## Affected packages

- `torch < 2.2.0`

## Remediation

Upgrade to a patched release:

- `torch 2.2.0`
