Kata Containers is an open source project focusing on a standard implementation of lightweight Virtual Machines (VMs) that perform like containers. In Kata Containers versions from 3.20.0 and before, a malicious host can circumvent initdata verification. On TDX systems running confidential guests, a malicious host can selectively fail IO operations to skip initdata verification. This allows an attacker to launch arbitrary workloads while being able to attest successfully to Trustee impersonating any benign workload. This issue has been patched in Kata Containers version 3.21.0.
CVE-2025-58354
This medium-severity CVE scores 6.9 under NVD CVSS v3. EPSS exploit probability: 0.3%, top 77% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
