Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: wwan: iosm: corregir la eliminación del puntero contaminado es un caso de error en la creación de la región. En caso de que falle la creación de la región en ipc_devlink_create_region(), el proceso de eliminación de regiones creadas previamente comienza desde el puntero contaminado que en realidad contiene el valor del código de error. Corrija este error disminuyendo el índice de región antes de eliminarlo. Encontrado por el Centro de verificación de Linux (linuxtesting.org) con SVACE.
