Astra Linux - уязвимость в qemu

An “off-by-one” error was detected in the SCSI device emulation in QEMU. This error could occur during the processing of MODE SELECT commands in modesensepage, if the ‘page’ argument is set to MODEPAGEALLS 0x3f. A malicious guest could exploit this flaw to potentially cause QEMU to crash, resulti...

QEMU through 8.0.0 could trigger a division by zero in scsi_disk_reset in hw/scsi/scsi-disk.c because scsi_disk_emulate_mode_select does not prevent s->qdev.blocksize from being 256. This stops QEMU and the guest immediately.
