Descriptions

The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel through 4.8.2 does not restrict a certain length field, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code.

La función arcmsr_iop_message_xfer en drivers/scsi/arcmsr/arcmsr_hba.c en el kernel de Linux hasta la versión 4.8.2 no restringe una cierta longitud de campo, lo que permite a usuarios locales obtener privilegios o provocar una denegación de servicio (desbordamiento de búfer basado en memoria dinámica) a través de un código de control ARCMSR_MESSAGE_WRITE_WQBUFFER.
