| Subject: CVE-2025-39930: ASoC: simple-card-utils: Don't use __free(device_node) at graph_util_parse_dai() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ASoC: simple-card-utils: Don't use __free(device_node) at graph_util_parse_dai() |
| |
| commit 419d1918105e ("ASoC: simple-card-utils: use __free(device_node) for |
| device node") uses __free(device_node) for dlc->of_node, but we need to |
| keep it while driver is in use. |
| |
| Don't use __free(device_node) in graph_util_parse_dai(). |
| |
| The Linux kernel CVE team has assigned CVE-2025-39930 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/232a32e8a7e9be8a2ee238df9b5304eed2f4e195 |
