| Subject: CVE-2024-42125: wifi: rtw89: fw: scan offload prohibit all 6 GHz channel if no 6 GHz sband |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: rtw89: fw: scan offload prohibit all 6 GHz channel if no 6 GHz sband |
| |
| We have some policy via BIOS to block uses of 6 GHz. In this case, 6 GHz |
| sband will be NULL even if it is WiFi 7 chip. So, add NULL handling here |
| to avoid crash. |
| |
| The Linux kernel CVE team has assigned CVE-2024-42125 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/ce4ba62f8bc5195a9a0d49c6235a9c99e619cadc |
