If\nthe work callback (_brcms_timer) is already running, cancel_delayed_work()\nreturns false without waiting, and brcms_free_timer() proceeds to kfree(t)\nwhile the callback still accesses t through container_of().\n\nAdd an explicit cancel_delayed_work_sync() after brcms_del_timer() to\nguarantee that any in-flight callback has completed before the timer\nstructure is freed.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/050d2486e8ed2c0a23b87249ccd23e8072721391","https://git.kernel.org/stable/c/10eeb0b29fd7f52487c9ae573e8d79c210a0095d","https://git.kernel.org/stable/c/1edb3ddd261e973a4d577c0547e63bfa25a8170d","https://git.kernel.org/stable/c/1eeca1d5e0920fbdad6449768fd2d4364e714180","https://git.kernel.org/stable/c/2a4841ff0b74b495cddd31ae324e922217fc2f13"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-98196","score":0.00177,"percentile":0.07153,"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).
