| Subject: CVE-2024-46714: drm/amd/display: Skip wbscl_set_scaler_filter if filter is null |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/amd/display: Skip wbscl_set_scaler_filter if filter is null |
| |
| Callers can pass null in filter (i.e. from returned from the function |
| wbscl_get_filter_coeffs_16p) and a null check is added to ensure that is |
| not the case. |
| |
| This fixes 4 NULL_RETURNS issues reported by Coverity. |
| |
| The Linux kernel CVE team has assigned CVE-2024-46714 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: |
