CVE-2025-37148
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability in the parsing of ethernet frames in AOS-8 Instant and AOS 10 could allow an unauthenticated remote attacker to conduct a denial of service attack. Successful exploitation could allow an attacker to potentially disrupt network services and require manual intervention to restore functionality.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA vulnerability in the ethernet frame parsing logic in AOS-8 Instant and AOS 10 allows an unauthenticated remote attacker to send specially crafted ethernet frames that cause a denial of service, requiring manual intervention to restore network services.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Aruba AOS product and versionRun 'show version' or access the controller CLI to identify the exact AOS version installed (e.g., AOS-8 Instant or AOS-10.x)Affected if The installed version is AOS-8 Instant or AOS 10 and falls within the affected version range for CVE-2025-37148 (compare your version to vendor advisories)
-
Identify ethernet interface exposureReview network configuration to determine if Layer 2 (ethernet) interfaces are directly accessible from untrusted network segments or the internetAffected if Ethernet interfaces are exposed to untrusted networks without ingress filtering or network segmentation
-
Check for network service disruptionUse 'show ap debug system-status' on controllers or monitor for unexpected controller/platform restarts or network outages that correlate with incoming ethernet frame trafficAffected if The device exhibits unexplained denial of service symptoms or requires manual intervention to restore network services
-
Verify interface statistics for anomaliesRun 'show interface' commands to inspect ethernet interface error counters, especially CRC errors, frame alignment errors, or input drops that may indicate malformed frame processingAffected if Interface statistics show abnormal error patterns consistent with malformed ethernet frame attacks
-
Review recent audit or system logsCheck system logs for entries related to ethernet frame processing errors, panic events, or unexpected process crashes around the time of service disruptionAffected if Logs contain entries indicating ethernet frame parsing failures or associated crash events
A user is affected if their Aruba AOS-8 Instant or AOS 10 device is exposed to untrusted network segments and exhibits unexplained Layer 2 service disruptions or requires manual restarts after receiving malformed ethernet frames.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-supplied patches for AOS-8 Instant and AOS 10 when available; until then, implement network segmentation and ingress filtering to limit exposure to untrusted network segments.
