A use-after-free vulnerability was found in the am53c974 SCSI host bus
adapter emulation of QEMU in versions before 6.0.0 during the handling of
the ‘Information Transfer’ command (CMD_TI). This flaw allows a privileged
guest user to crash the QEMU process on the host, resulting in a denial of
service or potential code execution with the privileges of the QEMU
process.
