CVE-2022-26073Public exploit

Device reboot via unchecked packet length

Published May 5, 2022 · Updated Apr 15, 2025

Integer overflow in Anker Innovations eufy HomeBase 2 2.1.8.5h allows remote attackers to reboot the device via crafted network packets. The libxm_av.so DemuxCmdInBuffer function adds 0xb to an unchecked WifiPkt.datalen value and advances its read pointer out of bounds, crashing home_security. Access requires presence on the HomeBase br0 device network or a bypass of its peer-MAC check; repeated process crashes trigger a full device reboot.
