Wireless-range reboot via NULL pointer dereference
Published Jan 7, 2026 · Updated Jan 7, 2026
NULL pointer dereference in Archer BE400 V1 802.11 modules through 1.1.0 Build 20250710 rel.14914 allows attackers to reboot the router. TP-Link has not disclosed which 802.11 input or code path supplies the null pointer that the firmware dereferences. Exploitation requires no authentication or user interaction, but the attacker must be within wireless range; a successful attempt interrupts service by rebooting the device.
