| Subject: CVE-2022-49239: ASoC: codecs: wcd934x: Add missing of_node_put() in wcd934x_codec_parse_data |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ASoC: codecs: wcd934x: Add missing of_node_put() in wcd934x_codec_parse_data |
| |
| The device_node pointer is returned by of_parse_phandle() with refcount |
| incremented. We should use of_node_put() on it when done. |
| This is similar to commit 64b92de9603f |
| ("ASoC: wcd9335: fix a leaked reference by adding missing of_node_put") |
| |
| The Linux kernel CVE team has assigned CVE-2022-49239 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: |
