| Subject: CVE-2025-37935: net: ethernet: mtk_eth_soc: fix SER panic with 4GB+ RAM |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: ethernet: mtk_eth_soc: fix SER panic with 4GB+ RAM |
| |
| If the mtk_poll_rx() function detects the MTK_RESETTING flag, it will |
| jump to release_desc and refill the high word of the SDP on the 4GB RFB. |
| Subsequently, mtk_rx_clean will process an incorrect SDP, leading to a |
| panic. |
| |
| Add patch from MediaTek's SDK to resolve this. |
| |
| The Linux kernel CVE team has assigned CVE-2025-37935 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: |
