In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: add upper bound check on user inputs in signal ioctl Huge input values in amdgpu_userq_signal_ioctl can lead to a OOM and could be exploited. So check these input value against AMDGPU_USERQ_MAX_HANDLES which is big enough value for genuine use cases and could potentially avoid OOM. (cherry picked from commit be267e15f99bc97cbe202cd556717797cdcf79a5)
