| Subject: CVE-2024-50206: net: ethernet: mtk_eth_soc: fix memory corruption during fq dma init |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: ethernet: mtk_eth_soc: fix memory corruption during fq dma init |
| |
| The loop responsible for allocating up to MTK_FQ_DMA_LENGTH buffers must |
| only touch as many descriptors, otherwise it ends up corrupting unrelated |
| memory. Fix the loop iteration count accordingly. |
| |
| The Linux kernel CVE team has assigned CVE-2024-50206 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/68cd084e3ec1512cd383cb3e9cf0ab7ab413724c |
