An off-by-one error was found in the SCSI device emulation in QEMU. It
could occur while processing MODE SELECT commands in mode_sense_page() if
the ‘page’ argument was set to MODE_PAGE_ALLS (0x3f). A malicious guest
could use this flaw to potentially crash QEMU, resulting in a denial of
service condition.
