Betreff: [PATCH v2] drm/amdgpu: check a user-provided number of BOs in list
The user can set any value to the variable ‘bo_number’, via the ioctl
The user can set any value to the variable ‘bo_number’, via the ioctl
command DRM_IOCTL_AMDGPU_BO_LIST. This will affect the arithmetic
expression ‘in->bo_number * in->bo_info_size’, which is prone to
overflow. Add a valid value check.
