CVE-2026-9105

An authenticated stack-based buffer overflow vulnerability exists in the web management interface of TP-Link TL-WR841N v14. A remote authenticated attacker can send crafted HTTP requests to cause the embedded web server to overflow a stack buffer, resulting in a crash of the affected process. Successful exploitation results in a denial-of-service condition, causing the device to crash and automatically reboot.
