Descriptions

In the Lustre file system before 2.12.3, the ptlrpc module has an out-of-bounds read and panic (via a modified lm_bufcount field) due to the lack of validation for specific fields of packets sent by a client. This is caused by interaction between sptlrpc_svc_unwrap_request and lustre_msg_hdr_size_v2.

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 (por medio de un campo lm_bufcount modificado) debido a la falta de comprobación para campos de paquetes específicos enviados mediante un cliente. Esto es causado por la interacción entre las funciones sptlrpc_svc_unwrap_request y lustre_msg_hdr_size_v2.
