n the Linux kernel, the following vulnerability has been resolved: gpio: prevent potential speculation leaks in gpio_device_get_desc() Userspace may trigger a speculative read of an address outside the gpio descriptor array. Users can do that by calling gpio_ioctl() with an offset out of range. Offset is copied from user and then used as an array index to get the gpio descriptor without sanitization in gpio_device_get_desc(). This change ensures that the offset is sanitized by using array_index_nospec() to mitigate any possibility of speculative information leaks. This bug was discovered and resolved using Coverity Static Analysis Security Testing (SAST) by Synopsys, Inc.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: gpio: evita posibles fugas de especulación en gpio_device_get_desc() El espacio de usuario puede desencadenar una lectura especulativa de una dirección fuera de la matriz de descriptores de gpio. Los usuarios pueden hacerlo llamando a gpio_ioctl() con un desplazamiento fuera de rango. La compensación se copia del usuario y luego se usa como índice de matriz para obtener el descriptor de gpio sin desinfección en gpio_device_get_desc(). Este cambio garantiza que la compensación se desinfecte mediante el uso de array_index_nospec() para mitigar cualquier posibilidad de fugas de información especulativa. Este error fue descubierto y resuelto utilizando Coverity Static Analysis Security Testing (SAST) por Synopsys, Inc.
