Vulnerability from cvelistv5 – Published: 2020-05-19 21:05 – Updated: 2024-09-16 19:35

Title

Kata Containers - Cloud Hypervisor guests persist filesystem changes to the underlying host image file

Summary

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.

Severity

8.8 (High)
