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.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/760bc6ceda8e2c273c0e2018ad2595967c3dd308","https://git.kernel.org/stable/c/a90d0dc38a10347078cca60e7495ad0648838f18","https://git.kernel.org/stable/c/e5235eb6cfe02a51256013a78f7b28779a7740d5"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:19:41.481987139+00:00"},"epss":{"cve":"CVE-2025-68762","score":0.00184,"percentile":0.07943,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
