| Subject: CVE-2024-35789: wifi: mac80211: check/clear fast rx for non-4addr sta VLAN changes |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: mac80211: check/clear fast rx for non-4addr sta VLAN changes |
| |
| When moving a station out of a VLAN and deleting the VLAN afterwards, the |
| fast_rx entry still holds a pointer to the VLAN's netdev, which can cause |
| use-after-free bugs. Fix this by immediately calling ieee80211_check_fast_rx |
| after the VLAN change. |
| |
| The Linux kernel CVE team has assigned CVE-2024-35789 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: |
