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.
Created kernel tracking bugs for this issue:
Affects: fedora-all [bug 1760492]
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
This is fixed in Fedora with the 5.4.7 stable kernel updates.
