| Subject: CVE-2024-42228: drm/amdgpu: Using uninitialized value *size when calling amdgpu_vce_cs_reloc |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/amdgpu: Using uninitialized value *size when calling amdgpu_vce_cs_reloc |
| |
| Initialize the size before calling amdgpu_vce_cs_reloc, such as case 0x03000001. |
| V2: To really improve the handling we would actually |
| need to have a separate value of 0xffffffff.(Christian) |
| |
| The Linux kernel CVE team has assigned CVE-2024-42228 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: |
