| Subject: CVE-2024-36955: ALSA: hda: intel-sdw-acpi: fix usage of device_get_named_child_node() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ALSA: hda: intel-sdw-acpi: fix usage of device_get_named_child_node() |
| |
| The documentation for device_get_named_child_node() mentions this |
| important point: |
| |
| " |
| The caller is responsible for calling fwnode_handle_put() on the |
| returned fwnode pointer. |
| " |
| |
| Add fwnode_handle_put() to avoid a leaked reference. |
| |
| The Linux kernel CVE team has assigned CVE-2024-36955 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: |
