| Subject: CVE-2024-56753: drm/amdgpu/gfx9: Add Cleaner Shader Deinitialization in gfx_v9_0 Module |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/amdgpu/gfx9: Add Cleaner Shader Deinitialization in gfx_v9_0 Module |
| |
| This commit addresses an omission in the previous patch related to the |
| cleaner shader support for GFX9 hardware. Specifically, it adds the |
| necessary deinitialization code for the cleaner shader in the |
| gfx_v9_0_sw_fini function. |
| |
| The added line amdgpu_gfx_cleaner_shader_sw_fini(adev); ensures that any |
| allocated resources for the cleaner shader are freed correctly, avoiding |
| potential memory leaks and ensuring that the GPU state is clean for the |
| next initialization sequence. |
| |
| The Linux kernel CVE team has assigned CVE-2024-56753 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/720c0376b3d29cbab921a60062fda5980742ed9d |
