CVE-2020-2025: Katacontainers Runtime

High severity, CVSS 8.8. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Katacontainers Runtime: before 1.11.0 (fixed in 1.11.0)
