A use-after-free vulnerability was found in the LSI53C895A SCSI Host Bus Adapter emulation of QEMU. The flaw occurs while processing repeated messages to cancel the current SCSI request via the lsi_do_msgout function. This flaw allows a malicious privileged user within the guest to crash the QEMU process on the host, resulting in a denial of service.

The qemu-kvm package versions as shipped with Red Hat Enterprise Linux and RHEL Advanced Virtualization are not affected by this issue, as they are not built with LSI53C895A support. Releases of Red Hat OpenStack Platform 15 and newer consume fixes directly from the Red Hat Enterprise Linux 8 Advanced Virtualization repository.
