| Subject: CVE-2024-49969: drm/amd/display: Fix index out of bounds in DCN30 color transformation |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/amd/display: Fix index out of bounds in DCN30 color transformation |
| |
| This commit addresses a potential index out of bounds issue in the |
| `cm3_helper_translate_curve_to_hw_format` function in the DCN30 color |
| management module. The issue could occur when the index 'i' exceeds the |
| number of transfer function points (TRANSFER_FUNC_POINTS). |
| |
| The fix adds a check to ensure 'i' is within bounds before accessing the |
| transfer function points. If 'i' is out of bounds, the function returns |
| false to indicate an error. |

| 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: |
