CVE-2026-18167 is a stack-based buffer overflow in the EasyMesh daemon of TP-Link Archer AX55 hardware version V4 routers. When EasyMesh/Mesh mode is enabled, the daemon insufficiently validates the length of an EasyMesh negotiation payload before copying it into a stack-based buffer. A local-network attacker can send an oversized crafted negotiation packet to crash the service and may be able to obtain code execution on the router's Linux-based operating system.

A high-severity stack-based buffer overflow in the TP-Link Archer AX55 V4 EasyMesh daemon that can enable root-level remote code execution from the local network when EasyMesh mode is enabled.
A High-severity stack-based buffer overflow in the EasyMesh service of TP-Link Archer AX55 hardware version V4. It requires local-network access and enabled Mesh mode; exploitation can cause denial of service and could potentially enable remote code execution on the router.
A high-severity stack-based buffer overflow in the EasyMesh service of TP-Link Archer AX55 hardware version V4. It can enable a local attacker to crash the easymesh daemon and, in some circumstances, achieve remote code execution on the router.
A stack-based buffer overflow in the EasyMesh module of TP-Link Archer AX55 v4. With Mesh mode enabled, a local-network attacker can submit crafted input to crash the easymesh daemon and potentially execute code on the router.
