Published: October 15, 2026
Vulnerability details
The vulnerability allows a local user to trigger a kernel warning.
The vulnerability exists due to an unnecessary warning assertion in ieee80211_request_ibss_scan() when requesting an IBSS scan with no channels permitted by the current regulatory domain. A local user can request a scan under this condition to trigger a kernel warning.
The regulatory domain can change while an IBSS is operating, and the IBSS can continue operating briefly during a 60-second grace period before shutdown.
