| Subject: CVE-2024-50295: net: arc: fix the device for dma_map_single/dma_unmap_single |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: arc: fix the device for dma_map_single/dma_unmap_single |
| |
| The ndev->dev and pdev->dev aren't the same device, use ndev->dev.parent |
| which has dma_mask, ndev->dev.parent is just pdev->dev. |
| Or it would cause the following issue: |
| |
| [ 39.933526] ------------[ cut here ]------------ |

| 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: |
