Published Oct 14, 2026 · corrected/updated Oct 15, 2026 · Linux Linux Kernel · evidence confidence high
From: Greg Kroah-Hartman Description =========== In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: don't warn when an IBSS has no channel to scan ieee80211_request_ibss_scan() warns when regulatory leaves no allowed channel, but that can happen as the regdomain can change while IBSS is operating, and it can continue to operate briefly during the 60s grace period until it's shut down. Just remove the warning in this case. The Linux kernel CVE team has assigned CVE-2026-98425 to this issue. Affected and fixed versions ========================
Grounded briefings
Catalog interpretations for three audiences. Each brief cites ingested metadata and the original advisories below. They are not independent research and they do not invent exploit steps.
Executive
