Description
The vulnerability allows a remote attacker to take over all guest operating systems on the hypervisor.
Kata Containers before 1.11.0 on Cloud Hypervisor persists guest filesystem changes to the underlying image file on the host. A malicious guest can overwrite the image file to gain control of all subsequent guest VMs. Since Kata Containers uses the same VM image file with all VMMs, this issue may also affect QEMU and Firecracker based guests.
Remediation
Install updates from vendor's website.
