| Subject: CVE-2022-48856: gianfar: ethtool: Fix refcount leak in gfar_get_ts_info |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| gianfar: ethtool: Fix refcount leak in gfar_get_ts_info |
| |
| The of_find_compatible_node() function returns a node pointer with |
| refcount incremented, We should use of_node_put() on it when done |
| Add the missing of_node_put() to release the refcount. |
| |
| The Linux kernel CVE team has assigned CVE-2022-48856 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: |
