CVE-2023-54141

Service interruption via unset IPQ5018 ring selector

Published Dec 24, 2025 · Updated Dec 24, 2025

NULL pointer dereference in the Linux kernel 6.3 ath11k driver allows attackers to crash IPQ5018 access points during data transmission. The IPQ5018 hardware-operations table leaves get_ring_selector unset, while ath11k_dp_tx calls it after a client connects and traffic is sent. Exposure requires an IPQ5018-based system using ath11k in access-point mode; the resulting kernel exception interrupts service.
