| Subject: CVE-2024-40941: wifi: iwlwifi: mvm: don't read past the mfuart notifcation |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: iwlwifi: mvm: don't read past the mfuart notifcation |
| |
| In case the firmware sends a notification that claims it has more data |
| than it has, we will read past that was allocated for the notification. |
| Remove the print of the buffer, we won't see it by default. If needed, |
| we can see the content with tracing. |
| |
| This was reported by KFENCE. |
| |
| The Linux kernel CVE team has assigned CVE-2024-40941 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: |
