| Subject: CVE-2024-27410: wifi: nl80211: reject iftype change with mesh ID change |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: nl80211: reject iftype change with mesh ID change |
| |
| It's currently possible to change the mesh ID when the |
| interface isn't yet in mesh mode, at the same time as |
| changing it into mesh mode. This leads to an overwrite |
| of data in the wdev->u union for the interface type it |
| currently has, causing cfg80211_change_iface() to do |
| wrong things when switching. |
| |
| We could probably allow setting an interface to mesh |
| while setting the mesh ID at the same time by doing a |
| different order of operations here, but realistically |
| there's no userspace that's going to do this, so just |
| disallow changes in iftype when setting mesh ID. |
| |
| The Linux kernel CVE team has assigned CVE-2024-27410 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: |
