CVE-2024-56753

Summary

CVE-2024-56753 is a vulnerability affecting the Linux kernel that has been addressed. This issue pertains to the drm/amdgpu/gfx9 driver and specifically the gfx_v9_0 module. Previously, a patch was implemented to support cleaner shaders for GFX9 hardware, but an omission in the code led to potential memory leaks. The new commit adds the missing deinitialization code, which is implemented in the function amdgpu_gfx_cleaner_shader_sw_fini(adev), ensuring that allocated resources for the cleaner shader are freed correctly, and the GPU state is clean for the next initialization sequence.
