Crafted UDP Packet Vulnerability in HPE Aruba Networking AOS-8
CVE-2026-79860 affects HPE Aruba Networking AOS-8 and can be triggered by sending specially crafted packets to UDP port 8211 on an affected system. The underlying weakness, vulnerable function, and resulting security impact have not been specified.
What it means and what to do now: patch path, interim mitigations, and the assume-compromise checklist.
If you can’t patch tonight, do this now.
HPE recommends isolating CLI and web management interfaces on a dedicated network segment or VLAN, enforcing firewall restrictions, and enabling activity accounting and logging. These bulletin-wide measures do not establish protection against the UDP port 8211 attack surface and do not replace patching. No CVE-specific interim workaround is specified.
Patch, then assume compromise.
Apply the AOS-8 security updates identified in HPE bulletin HPESBNW05162: upgrade to AOS-8.13.3.1 or later, or AOS-8.10.0.24 or later, within the applicable release branch. Migrate unsupported deployments to a supported, fixed release. Consult the bulletin for product-specific applicability.
