| Subject: CVE-2024-41061: drm/amd/display: Fix array-index-out-of-bounds in dml2/FCLKChangeSupport |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/amd/display: Fix array-index-out-of-bounds in dml2/FCLKChangeSupport |
| |
| [Why] |
| Potential out of bounds access in dml2_calculate_rq_and_dlg_params() |
| because the value of out_lowest_state_idx used as an index for FCLKChangeSupport |
| array can be greater than 1. |
| |
| [How] |
| Currently dml2 core specifies identical values for all FCLKChangeSupport |
| elements. Always use index 0 in the condition to avoid out of bounds access. |
| |
| The Linux kernel CVE team has assigned CVE-2024-41061 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/94166fe12543fbef122ca2d093e794ea41073a85 |
