Descriptions
In the Linux kernel, the following vulnerability has been resolved:
binder: make sure fd closes complete
During BC_FREE_BUFFER processing, the BINDER_TYPE_FDA object
cleanup may close 1 or more fds. The close operations are
completed using the task work mechanism -- which means the thread
needs to return to userspace or the file object may never be
dereferenced -- which can lead to hung processes.
Force the binder thread back to userspace if an fd is closed during
BC_FREE_BUFFER handling.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: carpeta: asegúrese de que fd se cierre por completo Durante el procesamiento BC_FREE_BUFFER, la limpieza del objeto BINDER_TYPE_FDA puede cerrar 1 o más fds. Las operaciones de cierre se completan utilizando el mecanismo de trabajo de tareas, lo que significa que el hilo debe regresar al espacio de usuario o es posible que nunca se elimine la referencia al objeto de archivo, lo que puede llevar a procesos bloqueados. Fuerce el hilo de la carpeta a regresar al espacio de usuario si se cierra un fd durante el manejo de BC_FREE_BUFFER.
