CVE-2026-23808
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 has been identified in a standardized wireless roaming protocol that could enable a malicious actor to install an attacker-controlled Group Temporal Key (GTK) on a client device. Successful exploitation of this vulnerability could allow a remote malicious actor to perform unauthorized frame injection, bypass client isolation, interfere with cross-client traffic, and compromise network segmentation, integrity, and confidentiality.
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 a standardized wireless roaming protocol allows a remote attacker to install a malicious Group Temporal Key (GTK) on client devices during the roaming or key installation process. This attacker-controlled GTK enables frame injection, bypass of client isolation, manipulation of cross-client traffic, and compromise of network segmentation.

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.
-
Identify the device OSAccess the device CLI or management interface and determine if the operating system is ArubaOS. Use commands like 'show version' or check the management UI for OS information.Affected if The device is not running ArubaOS - this vulnerability only affects ArubaOS devices.
-
Check ArubaOS version against affected rangesRun 'show version' in the ArubaOS CLI or check the management interface to obtain the exact OS version number.Affected if The installed version falls within any of these ranges: 6.5.4.0 to 8.10.0.21, 8.11.0.0 to 8.12.0.6, 8.13.0.0 to 8.13.1.1, 10.3.0.0 to 10.4.1.10, 10.5.0.0 to 10.7.2.2, or exactly version 10.8.0.0.
-
Verify wireless AP or controller role is enabledCheck the device configuration for active wireless access point (AP) or wireless controller functionality. In the CLI, commands like 'show ap active' or 'show controller-ip' can indicate active wireless roles.Affected if The device has no wireless AP or controller functionality enabled - the vulnerability requires wireless infrastructure roles to be active.
-
Confirm 802.11 wireless protocol is activeCheck that 802.11 wireless networks are configured and active on the device. Look for WLAN/Virtual AP configurations using 'show wlan' or 'show ap-config' commands.Affected if The device has no active 802.11 wireless networks configured - the vulnerable roaming protocol only applies when wireless clients can connect.
The environment is affected if the device runs ArubaOS within the listed version ranges and has active wireless AP or controller functionality with 802.11 networks enabled.

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-specific patches for affected wireless infrastructure devices; until patched, consider network segmentation, enhanced monitoring, and restricting wireless client-to-client communication.
