- Also known as: EUVD-2026-108383, GHSA-85HG-5FGV-284G
- Severity: CVSS 8.3 (High), CNA
- Vector: CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:H
- Known exploited (CISA KEV): no
- Published: 2026-10-22 · Updated: 2026-10-23

- Hewlett Packard Enterprise (HPE) ArubaOS (AOS): from 10.8.0.0, through 10.8.1.1; from 10.7.0.0, through 10.7.2.6; from 10.4.0.0, through 10.4.1.13

## Description

A buffer overflow vulnerability in the PAPI protocol of HPE Networking AOS-10 could allow an unauthenticated adjacent attacker to access sensitive information. Successful exploitation could allow an attacker to retrieve information which could be used to potentially gain further access to network services supported by AOS-10, and to interrupt the normal operation of the affected service.
