| Subject: CVE-2024-26822: smb: client: set correct id, uid and cruid for multiuser automounts |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| smb: client: set correct id, uid and cruid for multiuser automounts |
| |
| When uid, gid and cruid are not specified, we need to dynamically |
| set them into the filesystem context used for automounting otherwise |
| they'll end up reusing the values from the parent mount. |
| |
| The Linux kernel CVE team has assigned CVE-2024-26822 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/c2aa2718cda2d56b4a551cb40043e9abc9684626 |
