| Subject: CVE-2024-27432: net: ethernet: mtk_eth_soc: fix PPE hanging issue |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: ethernet: mtk_eth_soc: fix PPE hanging issue |
| |
| A patch to resolve an issue was found in MediaTek's GPL-licensed SDK: |
| In the mtk_ppe_stop() function, the PPE scan mode is not disabled before |
| disabling the PPE. This can potentially lead to a hang during the process |
| of disabling the PPE. |
| |
| Without this patch, the PPE may experience a hang during the reboot test. |
| |
| The Linux kernel CVE team has assigned CVE-2024-27432 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: |
