This leaves an embedded notifier block on the PM notifier chain\nafter the watchdog device has been unregistered.\n\nA later suspend/resume notification can then call watchdog_pm_notifier()\nwith a stale watchdog_device pointer, or at minimum after wdd->wd_data has\nbeen cleared by watchdog_dev_unregister().\n\nUnregister the PM notifier before tearing down the watchdog device.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/298821692d447c2f7b1bc9ef41cd88a31bf56436","https://git.kernel.org/stable/c/5d9b58ec6f5de5e159a570d419b1b08b3b9f854b","https://git.kernel.org/stable/c/89184909634e50d086d86d8a0c03fc86fe8d889f","https://git.kernel.org/stable/c/a298c7302ee9584a7a1ac1e8acbede8d98ab51a4","https://git.kernel.org/stable/c/c70b5bb6f04f77ef90e047d7edc2f476e206909f"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-74329","score":0.00215,"percentile":0.11853,"date":"2026-11-01"},"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).
