How to fix?

There is no fixed version for RHEL:7 libcacard-tools.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libcacard-tools package and not the libcacard-tools package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

An infinite loop flaw was found in the USB xHCI controller emulation of QEMU while computing the length of the Transfer Request Block (TRB) Ring. This flaw allows a privileged guest user to hang the QEMU process on the host, resulting in a denial of service.
