Critical Vulnerability Found in Wi-Fi Alliance Wireless Technology – Update Firmware Now

CVSScvssV3_1: 9.8

A critical vulnerability has been discovered in the way Wi-Fi Alliance wireless technology processes beacon signals from access points. The vulnerability, tracked as CVE-2023-33083, has a CVSS score of 9.8 out of 10 indicating its severity.

The vulnerability is a memory corruption issue that can occur when the wireless LAN host processes Radio Resource Management (RRM) beacon frames transmitted by the access point. By crafting malicious beacon frames, a remote attacker may be able to execute arbitrary code on the affected systems with kernel privileges.

This gives the attacker complete control of the victim’s device. They will then be able to steal sensitive information like passwords and credit card details, use the device to launch attacks on other systems, or encrypt and lock the device until a ransom is paid.

The vulnerability impacts devices that use Wi-Fi Alliance wireless technology from all major manufacturers. To protect yourself, ensure you keep your wireless network interface firmware up-to-date. Manufacturers have likely already released updates addressing this issue. You should also use a firewall and only connect to trusted networks you control.

By taking some basic steps like updating your firmware, you can help protect your devices and networks from this critical remote code execution vulnerability. Staying on top of security patches is important for your online safety.
