The devm cleanup then releases\nthe interrupt first, so the handler can no longer reschedule the work,\nand cancels the work before bq is freed. The explicit\ncancel_delayed_work_sync() in remove() is no longer needed and is dropped.\n\nFound by static analysis.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/47ccbad210f48721c30d69d65b83dc9fff919ca9","https://git.kernel.org/stable/c/6d2eb93975c07b0169a3287efc1ae3b60cf52d8e","https://git.kernel.org/stable/c/861ec73ce86e2ca18082cc7be4f140a5bbdf1428","https://git.kernel.org/stable/c/9d34c9d660c3d0931d2cc749c46c47cf31f96e48","https://git.kernel.org/stable/c/9d77fd7dd9a3ad57f7655c5264b503b85adbb7b8"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-89475","score":0.00211,"percentile":0.11304,"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).
