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 amdgpuuserqsignal_ioctl can lead to a OOM and could be exploited.
So check these input value against AMDGPUUSERQMAX_HANDLES which is big enough value for genuine use cases and could potentially avoid OOM.
(cherry picked from commit be267e15f99bc97cbe202cd556717797cdcf79a5)
