| Subject: CVE-2024-36021: net: hns3: fix kernel crash when devlink reload during pf initialization |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: hns3: fix kernel crash when devlink reload during pf initialization |
| |
| The devlink reload process will access the hardware resources, |
| but the register operation is done before the hardware is initialized. |
| So, processing the devlink reload during initialization may lead to kernel |
| crash. This patch fixes this by taking devl_lock during initialization. |
| |
| The Linux kernel CVE team has assigned CVE-2024-36021 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: |
