CVE-2026-4149
Full vulnerability record from the local CVENow database.
Description
Sonos Era 300 SMB Response Out-Of-Bounds Access Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Sonos Era 300. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the DataOffset field within SMB responses. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the kernel. Was ZDI-CAN-28345.

"value": "Vulnerabilidad de ejecución remota de código por acceso fuera de límites en la respuesta SMB de Sonos Era 300. Esta vulnerabilidad permite a atacantes remotos ejecutar código arbitrario en instalaciones afectadas de Sonos Era 300. La autenticación no es requerida para explotar esta vulnerabilidad.\n\nLa falla específica existe en el manejo del campo DataOffset dentro de las respuestas SMB. El problema resulta de la falta de validación adecuada de los datos proporcionados por el usuario, lo que puede resultar en un acceso a memoria más allá del final de un búfer asignado. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del kernel. Fue ZDI-CAN-28345."
