| Subject: CVE-2024-58092: nfsd: fix legacy client tracking initialization |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| nfsd: fix legacy client tracking initialization |
| |
| Get rid of the nfsd4_legacy_tracking_ops->init() call in |
| check_for_legacy_methods(). That will be handled in the caller |
| (nfsd4_client_tracking_init()). Otherwise, we'll wind up calling |
| nfsd4_legacy_tracking_ops->init() twice, and the second time we'll |
| trigger the BUG_ON() in nfsd4_init_recdir(). |
| |
| The Linux kernel CVE team has assigned CVE-2024-58092 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/95407304253a4bf03494d921c6913e220c26cc63 |
