| Subject: CVE-2024-58062: wifi: iwlwifi: mvm: avoid NULL pointer dereference |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: iwlwifi: mvm: avoid NULL pointer dereference |
| |
| When iterating over the links of a vif, we need to make sure that the |
| pointer is valid (in other words - that the link exists) before |
| dereferncing it. |
| Use for_each_vif_active_link that also does the check. |
| |
| The Linux kernel CVE team has assigned CVE-2024-58062 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: |
| https://git.kernel.org/stable/c/fbb563ad5032a07ac83c746ce5c8de5f25b5ffd0 |
