| Subject: CVE-2024-45028: mmc: mmc_test: Fix NULL dereference on allocation failure |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| mmc: mmc_test: Fix NULL dereference on allocation failure |
| |
| If the "test->highmem = alloc_pages()" allocation fails then calling |
| __free_pages(test->highmem) will result in a NULL dereference. Also |
| change the error code to -ENOMEM instead of returning success. |
| |
| The Linux kernel CVE team has assigned CVE-2024-45028 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: |
