However, drv_data allocation and workqueue allocation\ncan fail before intf_work, autowakeup_work and sleep_work have been\ninitialized.\n\nDo not enter the full remove path until the probe has reached the point\nwhere those work items are set up. Return directly for drv_data allocation\nfailure, and use a small early cleanup path for workqueue allocation\nfailure.\n\nThis issue was found by our static analysis tool and then confirmed by\nmanual review of rt2x00lib_probe_dev() and rt2x00lib_remove_dev(). The\nearly probe exits should not call a common teardown path that assumes the\nlater work setup has already completed.\n\nA QEMU PoC forced alloc_ordered_workqueue() to fail before the work\ninitializers are reached. The resulting fail path entered\nrt2x00lib_remove_dev(), and DEBUG_OBJECTS reported invalid work drains with\nrt2x00lib_probe_dev() and rt2x00lib_remove_dev() in the stack.","state":0,"publishedAt":"2026-08-15T05:51:36.005+00:00","modifiedAt":"2026-10-19T21:09:12.477+00:00","affected":[{"ecosystem":"Vendor
