CVE-2025-37852: drm/amdgpu: handle amdgpu_cgs_create_device() errors in amd_powerplay_create()
First published: Fri May 09 2025(Updated: )
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: handle amdgpu_cgs_create_device() errors in amd_powerplay_create() Add error handling to propagate amdgpu_cgs_create_device() failures to the caller. When amdgpu_cgs_create_device() fails, release hwmgr and return -ENOMEM to prevent null pointer dereference. [v1]->[v2]: Change error code from -EINVAL to -ENOMEM. Free hwmgr.
