| Subject: CVE-2024-46844: um: line: always fill *error_out in setup_one_line() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| um: line: always fill *error_out in setup_one_line() |
| |
| The pointer isn't initialized by callers, but I have |
| encountered cases where it's still printed; initialize |
| it in all possible cases in setup_one_line(). |

| 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: |
