Unauthenticated adjacent RCE in a widely used HPE/Aruba network OS that can fully compromise network devices and infrastructure.
CVE-2026-79865
Unauthenticated adjacent RCE in HPE AOS-10 enabling privileged code execution.
Is CVE-2026-79865 being exploited?
Not confirmed. CVE-2026-79865 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly. That is evidence of absence of a report, not evidence the flaw is unattacked. EPSS currently estimates a 0.35% probability of exploitation in the next 30 days.
How severe is CVE-2026-79865?
CVE-2026-79865 is rated Critical with a CVSS score of 9.6. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.
Is there a patch for CVE-2026-79865?
Not known from our data. No patch reference has been recorded for CVE-2026-79865, which is not the same as no patch existing — a fix may have shipped without a tagged reference, or after this record was written. The vendor advisory is the only authority on whether a fix exists, and mitigations may be available regardless.
What does CVE-2026-79865 affect?
CVE-2026-79865 affects HPE AOS-10, Aruba/HPE network OS devices. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
What should I do about CVE-2026-79865?
Apply vendor advisory mitigations and updates immediately; isolate affected devices and limit adjacent network access.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Unauthenticated adjacent attacker can execute arbitrary code as a privileged OS user, enabling full device compromise, network pivoting, and persistent access.

As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
