Description
In the Linux kernel, the following vulnerability has been resolved:
net/rds: reset op_nents when zerocopy page pin fails
When iov_iter_get_pages2() fails in rds_message_zcopy_from_user(),
the pinned pages are released with put_page(), and
rm->data.op_mmp_znotifier is cleared. But we fail to properly
clear rm->data.op_nents.
Later when rds_message_purge() is called from rds_sendmsg() the
cleanup loop iterates over the incorrectly non zero number of
op_nents and frees them again.
Fix this by properly resetting op_nents when it should be in
rds_message_zcopy_from_user().

Title: el kernel de Linux, Description: En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta:
net/rds: restablecer op_nents cuando falla el anclaje de página de copia cero
Cuando iov_iter_get_pages2() falla en rds_message_zcopy_from_user(), las páginas ancladas se liberan con put_page(), y rm->data.op_mmp_znotifier se borra. Pero no logramos borrar correctamente rm->data.op_nents.
Más tarde, cuando se llama a rds_message_purge() desde rds_sendmsg(), el bucle de limpieza itera sobre el número incorrectamente no cero de op_nents y los libera de nuevo.
Solucionar esto restableciendo correctamente op_nents cuando debería ser en rds_message_zcopy_from_user().
