| Subject: CVE-2024-41026: mmc: davinci_mmc: Prevent transmitted data size from exceeding sgm's length |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| mmc: davinci_mmc: Prevent transmitted data size from exceeding sgm's length |
| |
| No check is done on the size of the data to be transmiited. This causes |
| a kernel panic when this size exceeds the sg_miter's length. |
| |
| Limit the number of transmitted bytes to sgm->length. |
| |
| The Linux kernel CVE team has assigned CVE-2024-41026 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/c561c4ecce712f94b442db5960e281f13b28df2e |
