CVE-2022-50665

Adjacent service interruption via zeroed peer identifier

Published Dec 9, 2025 · Updated Aug 5, 2026

Improper initialization in Linux 5.18 allows physically proximate attackers to interrupt service by injecting Wi-Fi frames during scanning. ath11k_dp_rx_process_mon_status() zeroes ppdu_info but fails to restore peer_id to HAL_INVALID_PEERID, so peer ID 0 bypasses the invalid-peer check. The path requires an active Qualcomm ath11k radio; adjacent traffic can corrupt limited peer statistics and reach a kernel warning or oops.
