n the Linux kernel, the following vulnerability has been resolved: net: asix: add proper error handling of usb read errors Syzbot once again hit uninit value in asix driver. The problem still the same -- asix_read_cmd() reads less bytes, than was requested by caller. Since all read requests are performed via asix_read_cmd() let's catch usb related error there and add __must_check notation to be sure all callers actually check return value. So, this patch adds sanity check inside asix_read_cmd(), that simply checks if bytes read are not less, than was requested and adds missing error handling of asix_read_cmd() all across the driver code.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: asix: agregar manejo de errores adecuado para errores de lectura de USB Syzbot una vez más alcanzó un valor uninit en el controlador asix. El problema sigue siendo el mismo: asix_read_cmd() lee menos bytes de los que solicitó el llamador. Dado que todas las solicitudes de lectura se realizan a través de asix_read_cmd(), detectemos el error relacionado con USB allí y agreguemos la notación __must_check para asegurarnos de que todos los llamadores realmente verifiquen el valor de retorno. Entonces, este parche agrega una verificación de cordura dentro de asix_read_cmd(), que simplemente verifica si los bytes leídos no son menores que los solicitados y agrega la gestión de errores faltantes de asix_read_cmd() en todo el código del controlador.
