This software maintenance update (SMU) package delivers critical enhancements for Cisco Catalyst 9800 Series Wireless Controllers running IOS XE 17.1.5.1 base code. Designed as a hot patch, it implements protocol optimizations and security improvements without requiring controller reboots or service interruptions.

The package specifically addresses vulnerabilities in AP session handling and enhances 802.11ax (Wi-Fi 6E) resource allocation algorithms. Compatible with both standalone and high-availability deployments, it supports all Catalyst 9800 models including 9800-40, 9800-80, and 9800-CL cloud controllers.

Key Features and Improvements

  1. ​​Session Persistence Optimization​​
    Resolves AP session drops during high-density client handoffs (>5,000 simultaneous devices) through enhanced mobility tunnel management.

  2. ​​Security Enhancements​​

    • Patches CVE-2025-XXXXX: Buffer overflow in EAP-TLS validation
    • Implements stricter CAPWAP DTLS certificate verification

  3. ​​Radio Resource Management​​
