Description
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/pm/powerplay: bounds-check voltage index in SMU7 lookup vddInd and vddcInd fields from VBIOS-parsed tables are used to index into voltage lookup tables without a bounds check. Return -EINVAL when any index is out of range.
