| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ASoC: atmel: Add missing of_node_put() in at91sam9g20ek_audio_probe |
| |
| This node pointer is returned by of_parse_phandle() with refcount |

| 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: |
