The warning (at kernel/workqueue.c:4242 in\n__flush_work) occurs because the cleanup path tries to cancel an\nuninitialized work queue.\n\nWhen __netpoll_setup() encounters a device with IFF_DISABLE_NETPOLL,\nit fails early and calls skb_pool_flush() for cleanup. This function\ncalls cancel_work_sync(&np->refill_wq), but refill_wq hasn't been\ninitialized yet, triggering the warning.\n\nMove INIT_WORK() to the beginning of __netpoll_setup(), ensuring the\nwork queue is properly initialized before any potential failure points.\nThis allows the cleanup path to safely cancel the work queue regardless\nof where the setup fails.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
