| Subject: CVE-2024-35813: mmc: core: Avoid negative index with array access |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| mmc: core: Avoid negative index with array access |
| |
| Commit 4d0c8d0aef63 ("mmc: core: Use mrq.sbc in close-ended ffu") assigns |
| prev_idata = idatas[i - 1], but doesn't check that the iterator i is |
| greater than zero. Let's fix this by adding a check. |
| |
| The Linux kernel CVE team has assigned CVE-2024-35813 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: |
