      "value": "En el kernel de Linux, se resolvi\u00f3 la siguiente vulnerabilidad: gpio: evita posibles fugas de especulaci\u00f3n en gpio_device_get_desc() El espacio de usuario puede desencadenar una lectura especulativa de una direcci\u00f3n fuera de la matriz de descriptores de gpio. Los usuarios pueden hacerlo llamando a gpio_ioctl() con un desplazamiento fuera de rango. La compensaci\u00f3n se copia del usuario y luego se usa como \u00edndice de matriz para obtener el descriptor de gpio sin desinfecci\u00f3n en gpio_device_get_desc(). Este cambio garantiza que la compensaci\u00f3n se desinfecte mediante el uso de array_index_nospec() para mitigar cualquier posibilidad de fugas de informaci\u00f3n especulativa. Este error fue descubierto y resuelto utilizando Coverity Static Analysis Security Testing (SAST) por Synopsys, Inc."
