| Subject: CVE-2024-53127: Revert "mmc: dw_mmc: Fix IDMAC operation with pages bigger than 4K" |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| Revert "mmc: dw_mmc: Fix IDMAC operation with pages bigger than 4K" |
| |
| The commit 8396c793ffdf ("mmc: dw_mmc: Fix IDMAC operation with pages |
| bigger than 4K") increased the max_req_size, even for 4K pages, causing |
| various issues: |
| - Panic booting the kernel/rootfs from an SD card on Rockchip RK3566 |
| - Panic booting the kernel/rootfs from an SD card on StarFive JH7100 |
| - "swiotlb buffer is full" and data corruption on StarFive JH7110 |
| |
| At this stage no fix have been found, so it's probably better to just |
| revert the change. |
| |
| This reverts commit 8396c793ffdf28bb8aee7cfe0891080f8cab7890. |
| |
| The Linux kernel CVE team has assigned CVE-2024-53127 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: |
