| Subject: CVE-2025-37783: drm/msm/dpu: Fix error pointers in dpu_plane_virtual_atomic_check |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/msm/dpu: Fix error pointers in dpu_plane_virtual_atomic_check |
| |
| The function dpu_plane_virtual_atomic_check was dereferencing pointers |
| returned by drm_atomic_get_plane_state without checking for errors. This |
| could lead to undefined behavior if the function returns an error pointer. |
| |
| This commit adds checks using IS_ERR to ensure that plane_state is |
| valid before dereferencing them. |
| |
| Similar to commit da29abe71e16 |
| ("drm/amd/display: Fix error pointers in amdgpu_dm_crtc_mem_type_changed"). |

| 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/a9670ed1cce3216778c89936d3ae91cf0d436035 |
