| Subject: CVE-2025-37860: sfc: fix NULL dereferences in ef100_process_design_param() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| sfc: fix NULL dereferences in ef100_process_design_param() |
| |
| Since cited commit, ef100_probe_main() and hence also |
| ef100_check_design_params() run before efx->net_dev is created; |
| consequently, we cannot netif_set_tso_max_size() or _segs() at this |
| point. |
| Move those netif calls to ef100_probe_netdev(), and also replace |
| netif_err within the design params code with pci_err. |
| |
| The Linux kernel CVE team has assigned CVE-2025-37860 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: |
