How to fix?

There is no fixed version for RHEL:7 qemu-kvm-common-rhev.

NVD Description

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

A flaw was found in QEMU in the implementation of the Pointer Authentication (PAuth) support for ARM introduced in version 4.0 and fixed in version 5.0.0. A general failure of the signature generation process caused every PAuth-enforced pointer to be signed with the same signature. A local attacker could obtain the signature of a protected pointer and abuse this flaw to bypass PAuth protection for all programs running on QEMU.
