| Subject: CVE-2024-58012: ASoC: SOF: Intel: hda-dai: Ensure DAI widget is valid during params |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ASoC: SOF: Intel: hda-dai: Ensure DAI widget is valid during params |
| |
| Each cpu DAI should associate with a widget. However, the topology might |
| not create the right number of DAI widgets for aggregated amps. And it |
| will cause NULL pointer deference. |
| Check that the DAI widget associated with the CPU DAI is valid to prevent |
| NULL pointer deference due to missing DAI widgets in topologies with |
| aggregated amps. |
| |
| The Linux kernel CVE team has assigned CVE-2024-58012 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/e012a77e4d7632cf615ba9625b1600ed8985c3b5 |
