| Subject: CVE-2024-38551: ASoC: mediatek: Assign dummy when codec not specified for a DAI link |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ASoC: mediatek: Assign dummy when codec not specified for a DAI link |
| |
| MediaTek sound card drivers are checking whether a DAI link is present |
| and used on a board to assign the correct parameters and this is done |
| by checking the codec DAI names at probe time. |
| |
| If no real codec is present, assign the dummy codec to the DAI link |
| to avoid NULL pointer during string comparison. |
| |
| The Linux kernel CVE team has assigned CVE-2024-38551 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/87b8dca6e06f9b1681bc52bf7bfa85c663a11158 |
