| Subject: CVE-2024-58001: ocfs2: handle a symlink read error correctly |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ocfs2: handle a symlink read error correctly |
| |
| Patch series "Convert ocfs2 to use folios". |
| |
| Mark did a conversion of ocfs2 to use folios and sent it to me as a |
| giant patch for review ;-) |
| |
| So I've redone it as individual patches, and credited Mark for the patches |
| where his code is substantially the same. It's not a bad way to do it; |
| his patch had some bugs and my patches had some bugs. Hopefully all our |
| bugs were different from each other. And hopefully Mark likes all the |
| changes I made to his code! |
| |

| 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: |
