ArubaOS (AOS): Out-of-bounds Read
CVE-2025-37178 is a high-severity out-of-bounds read vulnerability in ArubaOS (AOS) from Hewlett Packard Enterprise, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected ArubaOS (AOS) versions: 8.12.0.0 through 8.13.1.0; 8.10.0.0 through 8.10.0.20. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.39% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Arubaos to 8.10.0.21 or 8.13.1.1, whichever matches your release line, or a later version.
- Read the advisory on support.hpe.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
Multiple out-of-bounds read vulnerabilities were identified in a system component responsible for handling certain data buffers. Due to insufficient validation of maximum buffer size values, the process may attempt to read beyond the intended memory region. Under specific conditions, this can result in a crash of the affected process and a potential denial-of-service of the compromised process.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Out-of-bounds Read
The product reads data past the end, or before the beginning, of the intended buffer.
How developers prevent this class of flaw
- Use a language that provides appropriate memory abstractions.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: yes, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
