A NULL pointer dereference issue was found in the megasas-gen2 SCSI host bus adapter emulation of QEMU. It could occur in the megasas_command_cancelled() callback function in hw/scsi/megasas.c while dropping a SCSI request. A privileged guest user may exploit this issue to crash the QEMU process on the host, resulting in a denial of service condition.
