| Subject: CVE-2024-42074: ASoC: amd: acp: add a null check for chip_pdev structure |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ASoC: amd: acp: add a null check for chip_pdev structure |
| |
| When acp platform device creation is skipped, chip->chip_pdev value will |
| remain NULL. Add NULL check for chip->chip_pdev structure in |
| snd_acp_resume() function to avoid null pointer dereference. |
| |
| The Linux kernel CVE team has assigned CVE-2024-42074 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: |
