AI-suggested

A patch is available and has been released in multiple 5.15.x Linux kernel versions. Users should update their Linux kernel to one of the fixed versions listed (e.g., 5.15.0-1073.79~20.04.1 or later). Applying the official kernel updates from the vendor (Ubuntu) will remediate this issue. No additional mitigation steps are required beyond applying the official fixes.

Description

CVE-2024-47673 is a vulnerability in the Linux kernel's iwlwifi driver where the TCM (Traffic Control Module) is not paused when the firmware is stopped. This can cause the system to send host commands to the transport layer while the firmware is inactive, triggering a kernel warning and potentially causing instability. The issue affects multiple Linux kernel versions and has been fixed in several 5.15.x releases. The vulnerability has a medium severity with a CVSS score of 5.5 and does not impact confidentiality or integrity but affects availability.
