Upgrade Centos:8 qemu-img to version 15:6.2.0-49.module+el8.10.0+21533+3df3c4b6 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream qemu-img package and not the qemu-img package as distributed by Centos.
See How to fix? for Centos:8 relevant fixed versions and status.
A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead (potentially overwriting the VM's boot code). This could be used, for example, by L2 guests with a virtual disk (vdiskL2) stored on a virtual disk of an L1 (vdiskL1) hypervisor to read and/or write data to LBA 0 of vdiskL1, potentially gaining control of L1 at its next reboot.
