+assertion failure in lsi53c810 emulator
+
+Hello,
+
+Using hypervisor fuzzer, hyfuzz, I found an assertion failure through lsi53c810 emulator.
+
+A malicious guest user/process could use this flaw to abort the QEMU process on the host, resulting in a denial of service.
+
+This was found in version 5.2.0 (master)
+
+
+qemu-system-i386: ../hw/scsi/lsi53c895a.c:624: void lsi_do_dma(LSIState *, int): Assertion `s->current'
+failed.

+
+Program terminated with signal SIGABRT, Aborted.

+To reproduce this issue, please run the QEMU with the following command line.
+
+
+# To enable ASan option, please set configuration with the following command
+$ ./configure --target-list=i386-softmmu --disable-werror --enable-sanitizers
+$ make
+
+# To reproduce this issue, please run the QEMU process with the following command line.
+$ ./qemu-system-i386 -m 512 -drive file=./hyfuzz.img,index=0,media=disk,format=raw -device lsi53c810,id=scsi -device scsi-hd,drive=SysDisk -drive id=SysDisk,if=none,file=./disk.img
+
+Please let me know if I can provide any further info.
+Thank you.
