| Subject: CVE-2025-21924: net: hns3: make sure ptp clock is unregister and freed if hclge_ptp_get_cycle returns an error |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: hns3: make sure ptp clock is unregister and freed if hclge_ptp_get_cycle returns an error |
| |
| During the initialization of ptp, hclge_ptp_get_cycle might return an error |
| and returned directly without unregister clock and free it. To avoid that, |
| call hclge_ptp_destroy_clock to unregist and free clock if |
| hclge_ptp_get_cycle failed. |
| |
| The Linux kernel CVE team has assigned CVE-2025-21924 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: |
