Impact
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: add upper bound check on user inputs in wait ioctl Huge input values in amdgpu_userq_wait_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. v2: squash in Srini's fix (cherry picked from commit fcec012c664247531aed3e662f4280ff804d1476)
