Name of the Vulnerable Software and Affected Versions Kata Containers versions prior to 1.11.0

Description The issue allows a malicious guest to persist filesystem changes to the underlying image file on the host, potentially gaining control of subsequent guest VMs. This is particularly concerning since Kata Containers uses the same VM image file across different VMMs, which may also impact QEMU and Firecracker based guests.

Recommendations For versions prior to 1.11.0, update to version 1.11.0 or later to resolve the issue.
