| Subject: CVE-2024-40929: wifi: iwlwifi: mvm: check n_ssids before accessing the ssids |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: iwlwifi: mvm: check n_ssids before accessing the ssids |
| |
| In some versions of cfg80211, the ssids poinet might be a valid one even |
| though n_ssids is 0. Accessing the pointer in this case will cuase an |
| out-of-bound access. Fix this by checking n_ssids first. |
| |
| The Linux kernel CVE team has assigned CVE-2024-40929 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: |
