## Overview

An integer overflow in util-linux through 2.37.1 can potentially cause a buffer overflow if an attacker were able to use system resources in a way that leads to a large number in the /proc/sysvipc/sem file. NOTE: this is unexploitable in GNU C Library environments, and possibly in all realistic environments.

## Affected

- `util-linux <= 2.37.1`
- `ontap_select_deploy_administration_utility`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
