| Subject: CVE-2024-36970: wifi: iwlwifi: Use request_module_nowait |
| |
| 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] |
| |
| The Linux kernel CVE team has assigned CVE-2024-36970 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
| https://git.kernel.org/stable/c/d20013259539e2fde2deeac85354851097afdf9e |
