This can result in a\nNULL pointer dereference if client->ops is NULL.\n\nFix by adding the missing client->ops check in both the teardown\nand teardown_late labels.","state":0,"publishedAt":"2026-10-23T11:37:21.776+00:00","modifiedAt":"2026-10-23T11:37:21.776+00:00","affected":[{"ecosystem":"Vendor
