| Subject: CVE-2024-35913: wifi: iwlwifi: mvm: pick the version of SESSION_PROTECTION_NOTIF |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: iwlwifi: mvm: pick the version of SESSION_PROTECTION_NOTIF |
| |
| When we want to know whether we should look for the mac_id or the |
| link_id in struct iwl_mvm_session_prot_notif, we should look at the |
| version of SESSION_PROTECTION_NOTIF. |
| |
| This causes WARNINGs: |
| |

| 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: |
