| Subject: CVE-2025-21651: net: hns3: don't auto enable misc vector |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: hns3: don't auto enable misc vector |
| |
| Currently, there is a time window between misc irq enabled |
| and service task inited. If an interrupte is reported at |
| this time, it will cause warning like below: |
| |
| [ 16.324639] Call trace: |
| [ 16.324641] __queue_delayed_work+0xb8/0xe0 |
| [ 16.324643] mod_delayed_work_on+0x78/0xd0 |

| |
| So don't auto enable misc vector when request irq.. |

| 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/bcf430d3bb5525fc89a92a0c451c725ba1aa4306 |
