Transient service interruption via invalid CSA channel
Published Sep 5, 2023 · Updated Aug 2, 2024
Denial of service in Qualcomm WLAN Host allows remote attackers to interrupt wireless service by sending an invalid channel in a CSA element. The mobile-station host processes that invalid channel while handling a Channel Switch Announcement information element, producing a transient denial of service instead of rejecting the announcement. The attack requires WLAN radio reachability and affects availability only; Qualcomm has not published a more specific failure mode than the transient interruption.
