| Subject: CVE-2022-49477: ASoC: samsung: Fix refcount leak in aries_audio_probe |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ASoC: samsung: Fix refcount leak in aries_audio_probe |
| |
| of_parse_phandle() returns a node pointer with refcount |
| incremented, we should use of_node_put() on it when done. |
| If extcon_find_edev_by_node() fails, it doesn't call of_node_put() |
| Calling of_node_put() after extcon_find_edev_by_node() to fix this. |
| |
| The Linux kernel CVE team has assigned CVE-2022-49477 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: |
