| Subject: CVE-2024-42119: drm/amd/display: Skip finding free audio for unknown engine_id |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/amd/display: Skip finding free audio for unknown engine_id |
| |
| [WHY] |
| ENGINE_ID_UNKNOWN = -1 and can not be used as an array index. Plus, it |
| also means it is uninitialized and does not need free audio. |

| ========== |
| |
| 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: |
