What it is stated by the CNA
In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: Lock wiphy in cfg80211_get_station Wiphy should be locked before calling rdev_get_station() (see lockdep assert in ieee80211_get_station()).

How to check this
Every value above is held with two dates: when it was true upstream (as_of) and when we recorded it (tx_from). Re-derive the exploit probability as it stood on any date:
SELECT value, source, source_version, as_of, tx_from
FROM volatile_valid_as_of('CVE-2024-40911', '2026-10-31T23:59:59.999999Z', now());
