| Subject: CVE-2024-39473: ASoC: SOF: ipc4-topology: Fix input format query of process modules without base extension |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ASoC: SOF: ipc4-topology: Fix input format query of process modules without base extension |
| |
| If a process module does not have base config extension then the same |
| format applies to all of it's inputs and the process->base_config_ext is |
| NULL, causing NULL dereference when specifically crafted topology and |
| sequences used. |
| |
| The Linux kernel CVE team has assigned CVE-2024-39473 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/e3ae00ee238bce6cfa5ad935c921181c14d18fd6 |
