| Subject: CVE-2024-27434: wifi: iwlwifi: mvm: don't set the MFP flag for the GTK |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: iwlwifi: mvm: don't set the MFP flag for the GTK |
| |
| The firmware doesn't need the MFP flag for the GTK, it can even make the |
| firmware crash. in case the AP is configured with: group cipher TKIP and |
| MFPC. We would send the GTK with cipher = TKIP and MFP which is of course |
| not possible. |
| |
| The Linux kernel CVE team has assigned CVE-2024-27434 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: |
