| Subject: CVE-2025-22054: arcnet: Add NULL check in com20020pci_probe() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| arcnet: Add NULL check in com20020pci_probe() |
| |
| devm_kasprintf() returns NULL when memory allocation fails. Currently, |
| com20020pci_probe() does not check for this case, which results in a |
| NULL pointer dereference. |
| |
| Add NULL check after devm_kasprintf() to prevent this issue and ensure |
| no resources are left allocated. |
| |
| The Linux kernel CVE team has assigned CVE-2025-22054 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: |
