Doc Text:
A NULL pointer dereference flaw was found in kfd_interrupt_init in drivers/gpu/drm/amd/amdkfd/kfd_interrupt.c in AMD GPU driver. Here a call to alloc_workqueue return was not validated and can cause a denial of service at the time of failure. This could allow an attacker to crash the system or leak kernel internal information.
