      "value": "A stack-based buffer overflow vulnerability exists in the mtk_dut binary of Linksys E7350 routers (Firmware 1.1.00.032). The function sub_4045A8 reads up to 256 bytes from /sys/class/net/%s/address into a local buffer and then copies it into caller-provided buffer a1 using strcpy without boundary checks. Since a1 is often allocated with significantly smaller sizes (20-32 bytes), local attackers controlling the contents of /sys/class/net/%s/address can trigger buffer overflows, leading to memory corruption, denial of service, or potential arbitrary code execution."

      "value": "Una vulnerabilidad de desbordamiento de búfer basado en pila existe en el binario mtk_dut de los routers Linksys E7350 (Firmware 1.1.00.032). La función sub_4045A8 lee hasta 256 bytes de /sys/class/net/%s/address en un búfer local y luego lo copia en el búfer a1 proporcionado por el llamador usando strcpy sin comprobaciones de límites. Dado que a1 a menudo se asigna con tamaños significativamente menores (20-32 bytes), los atacantes locales que controlan el contenido de /sys/class/net/%s/address pueden desencadenar desbordamientos de búfer, lo que lleva a corrupción de memoria, denegación de servicio o potencial ejecución de código arbitrario."
