| Subject: CVE-2024-43912: wifi: nl80211: disallow setting special AP channel widths |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: nl80211: disallow setting special AP channel widths |

| 20/40/... MHz channel width progression, and switching around |
| in S1G or narrow channels isn't supported. Disallow that. |

| 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: |
