Vulnerability Title
wifi: iwlwifi: Use request_module_nowait
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: Use request_module_nowait This appears to work around a deadlock regression that came in with the LED merge in 6.9. The deadlock happens on my system with 24 iwlwifi radios, so maybe it something like all worker threads are busy and some work that needs to complete cannot complete. [also remove unnecessary "load_module" var and now-wrong comment]
