WLAN Access Point and Station firmware are vulnerable to an uncaught exception that can cause the system to stop responding, disrupting wireless connectivity.

The WLAN firmware (Access Point/Station) contains an uncaught exception vulnerability. An unauthenticated attacker could potentially trigger this exception through malicious wireless frames or network traffic, causing the device to enter an unresponsive state.

The vulnerability leads to a loss of wireless connectivity for all clients associated with the affected Access Point. With a CVSS score of 7.5, this poses a significant risk to organizational productivity and the reliability of the wireless local area network (WLAN).

Immediate Action: Update the AP and STA firmware to the latest versions provided by the hardware manufacturer to resolve the exception handling flaw.

Proactive Monitoring: Use wireless network management tools to monitor AP responsiveness and investigate any devices that stop responding to pings or management queries.

Compensating Controls: Implement strong WPA3 encryption and management frame protection (MFP) to reduce the ability of unauthorized devices to interact with the firmware's management logic.

Public Exploit Available: false

Organizations should prioritize the update of wireless infrastructure firmware. Given the High-severity rating, failing to patch could lead to widespread wireless outages that are difficult to diagnose without physical access to the hardware.
