A high-severity memory handling vulnerability in the Linux kernel mwifiex driver could allow an adjacent attacker to trigger system instability or remote code execution.

This is a memory-related flaw in the mwifiex Wi-Fi driver, specifically within the A-MSDU frame parsing logic. The vulnerability is exploitable by an unauthenticated adjacent attacker (AV:A/AC:L/PR:N/UI:N).

Successful exploitation of this kernel-level vulnerability could lead to a complete system compromise, including unauthorized access to data or denial of service. With a CVSS score of 8.8, this flaw represents a significant risk to internal network infrastructure where affected Wi-Fi hardware is deployed.

Immediate Action: Update the Linux kernel to version 6.6.151, 6.12.103, 6.18.44, 7.1.8, or newer, as provided by your distribution vendor.

Proactive Monitoring: Monitor system logs for kernel panics or unexpected process terminations related to the mwifiex driver.

Compensating Controls: Restrict access to wireless network segments to trusted devices and monitor for unusual traffic patterns targeting Wi-Fi management frames.

Public Exploit Available: No

Given the severity of kernel-level vulnerabilities, organizations should prioritize the deployment of patched kernel images. Ensure that all wireless infrastructure components running the affected Linux kernel versions are updated during the next maintenance window to eliminate this attack vector.
