CVE-2026-9105: CWE-121 Stack-based buffer overflow in TP-Link Systems Inc. TL-WR841N v14
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.
AI Analysis
Technical Summary
This vulnerability is an authenticated stack-based buffer overflow in the embedded web server of the TP-Link TL-WR841M v14 device. A remote attacker with valid credentials can send specially crafted HTTP requests to trigger a stack buffer overflow, causing the web management process to crash. The crash leads to a denial-of-service condition by forcing the device to reboot. The CVSS 4.0 vector indicates the attack requires adjacent network access, low attack complexity, no user interaction, and high impact on availability. No official fix or patch has been disclosed as of the publication date.
Potential Impact
Successful exploitation results in denial-of-service by crashing the web management process and causing the device to reboot automatically. This disrupts normal device operation and management availability. There is no indication of code execution or data compromise from the provided information.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the device's management interface to trusted administrators and networks to reduce risk. Monitor vendor channels for updates or official patches.
