Descriptions

In the Lustre file system before 2.12.3, the ptlrpc module has an out-of-bounds read and panic due to the lack of validation for specific fields of packets sent by a client. The ldl_request_cancel function mishandles a large lock_count parameter.

En el sistema de archivos de Luster versiones anteriores versiones hasta 2.12.3, el módulo ptlrpc presenta una lectura fuera de límites y un pánico debido a la falta de comprobación para campos de paquetes específicos enviados mediante un cliente. La función ldl_request_cancel maneja inapropiadamente un parámetro lock_count grande.
