| Subject: CVE-2024-50166: fsl/fman: Fix refcount handling of fman-related devices |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| fsl/fman: Fix refcount handling of fman-related devices |
| |
| In mac_probe() there are multiple calls to of_find_device_by_node(), |
| fman_bind() and fman_port_bind() which takes references to of_dev->dev. |
| Not all references taken by these calls are released later on error path |
| in mac_probe() and in mac_remove() which lead to reference leaks. |
| |
| Add references release. |
| |
| The Linux kernel CVE team has assigned CVE-2024-50166 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: |
| https://git.kernel.org/stable/c/5ed4334fc9512f934fe2ae9c4cf7f8142e451b8b |
