CVE-2024-47672 is a medium-severity vulnerability in the Linux kernel's iwlwifi driver. It involves improper handling of transmission (TX) queues when the firmware is dead, leading to a warning condition. The flaw occurs because the driver waits for TX queues to empty even after the firmware has stopped responding, which is not appropriate. The fix prevents waiting on TX queues if the firmware is dead, while still allowing necessary maintenance operations to continue.
