| Subject: CVE-2023-52583: ceph: fix deadlock or deadcode of misusing dget() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ceph: fix deadlock or deadcode of misusing dget() |
| |
| The lock order is incorrect between denty and its parent, we should |
| always make sure that the parent get the lock first. |
| |
| But since this deadcode is never used and the parent dir will always |
| be set from the callers, let's just remove it. |
| |
| The Linux kernel CVE team has assigned CVE-2023-52583 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: |
