 kthreads_online_cpu+0x140/0x140 ret_from_fork_asm+0x11/0x20 </TASK> The cause of this is: -
 drm_prime_gem_destroy calls dma_buf_put(dma_buf) which releases the reference to the shared dma_buf. The
 reference count is 0, so the dma_buf is destroyed, which in turn decrements the corresponding amdgpu_bo
 reference count to 0, and the amdgpu_bo is destroyed - calling drm_gem_object_release then dma_resv_fini
 (which destroys the reservation object), then finally freeing the amdgpu_bo. - nouveau_bo
 obj->bo.base.resv is now a dangling pointer to the memory formerly allocated to the amdgpu_bo. -
 nouveau_gem_object_del calls ttm_bo_put(&nvbo->bo) which calls ttm_bo_release, which schedules
 ttm_bo_delayed_delete. - ttm_bo_delayed_delete runs and dereferences the dangling resv pointer, resulting
 in a general protection fault. Fix this by moving the drm_prime_gem_destroy call from
 nouveau_gem_object_del to nouveau_bo_del_ttm. This ensures that it will be run after
 ttm_bo_delayed_delete. (CVE-2025-37765)
