| Subject: CVE-2024-47673: wifi: iwlwifi: mvm: pause TCM when the firmware is stopped |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: iwlwifi: mvm: pause TCM when the firmware is stopped |
| |
| Not doing so will make us send a host command to the transport while the |
| firmware is not alive, which will trigger a WARNING. |
| |
| bad state = 0 |

| 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/a15df5f37fa3a8b7a8ec7a339d1e897bc524e28f |
