Description

In the Linux kernel, the following vulnerability has been resolved: accel/ivpu: Fix page fault in ivpu_bo_unbind_all_bos_from_context() Don't add BO to the vdev->bo_list in ivpu_gem_create_object(). When failure happens inside drm_gem_shmem_create(), the BO is not fully created and ivpu_gem_bo_free() callback will not be called causing a deleted BO to be left on the list.
