| Subject: CVE-2024-27056: wifi: iwlwifi: mvm: ensure offloading TID queue exists |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: iwlwifi: mvm: ensure offloading TID queue exists |
| |
| The resume code path assumes that the TX queue for the offloading TID |
| has been configured. At resume time it then tries to sync the write |
| pointer as it may have been updated by the firmware. |
| |
| In the unusual event that no packets have been send on TID 0, the queue |
| will not have been allocated and this causes a crash. Fix this by |
| ensuring the queue exist at suspend time. |
| |
| The Linux kernel CVE team has assigned CVE-2024-27056 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: |
