CVE-2026-76649 1 Tp-link 1 Tl-wr841n V14 2026-09-01 N/A
A NULL pointer dereference vulnerability exists in TL-WR841N v14 in the UPnP service when processing SOAP action requests. A specially crafted SOAP action request containing unexpected XML content may cause the UPnP daemon to terminate unexpectedly. Successful exploitation may result in a denial-of-service condition affecting UPnP functionality until the service is restarted or the device is rebooted.
CVE-2026-76650 1 Tp-link 1 Tl-wr841n V14 2026-09-01 N/A
A NULL pointer dereference vulnerability exists in TL-WR841N v14 in the UPnP service when processing SOAP state variable query requests. A specially crafted SOAP query may trigger unexpected termination or instability of the process hosting the UPnP service. Successful exploitation may result in a denial-of-service condition affecting UPnP discovery, state query, or related management functionality until the affected process is restarted or the device is rebooted.
CVE-2026-76651 1 Tp-link 1 Tl-wr841n V14 2026-09-01 N/A
A buffer overflow vulnerability exists in the embedded HTTP service in TL-WR841N v14 when processing multipart/form-data requests. Insufficient validation of an attacker-controlled boundary parameter may allow a remote unauthenticated attacker to submit a crafted request that corrupts memory by overwriting data beyond the bounds of an internal buffer. Successful exploitation may result in modification or corruption of process memory, potentially leading to undefined application behavior. Arbitrary code execution, information disclosure, and denial-of-service conditions have not been demonstrated.
CVE-2026-9105 1 Tp-link 3 Tl-wr841n, Tl-wr841n Firmware, Tl-wr841n V14 2026-07-01 6.5 Medium
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.
CVE-2026-3622 1 Tp-link 3 Tl-wr841n, Tl-wr841n Firmware, Tl-wr841n V14 2026-04-02 7.5 High
The vulnerability exists in the UPnP component of TL-WR841N v14, where improper input validation leads to an out-of-bounds read, potentially causing a crash of the UPnP service. Successful exploitation can cause the UPnP service to crash, resulting in a Denial-of-Service condition.  This vulnerability affects TL-WR841N v14 < EN_0.9.1 4.19 Build 260303 Rel.42399n (V14_260303) and < US_0.9.1.4.19 Build 260312 Rel. 49108n (V14_0304).
