KubeVirt vs Clair: at a glance
What is KubeVirt?
KubeVirt 1.10 hits rc.1 with incremental VM backup in beta and a port-forward CVE fixed.
KubeVirt runs a long pre-release cycle per minor version, and 1.10 is now at rc.1 (12 November) with 1,761 changes from 104 contributors since 1.9.1. The cycle centres on VM data protection: incremental backup and the backup API move to beta, offline incremental backup and an External snapshot mode arrive. rc.1 also lists a fix for an SSRF flaw (CVE-2026-13318) that let a malicious guest agent redirect virtctl port-forward and ssh traffic.
What is Clair?
Clair 4.10 RC can read SBOMs to match Java vulnerabilities.
Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.

KubeVirt 1.10 hits rc.1 with incremental VM backup in beta and a port-forward CVE fixed.
◆ Current state
KubeVirt runs a long pre-release cycle per minor version, and 1.10 is now at rc.1 (12 November) with 1,761 changes from 104 contributors since 1.9.1. The cycle centres on VM data protection: incremental backup and the backup API move to beta, offline incremental backup and an External snapshot mode arrive. rc.1 also lists a fix for an SSRF flaw (CVE-2026-13318) that let a malicious guest agent redirect virtctl port-forward and ssh traffic.
◆ Where it's heading
1.10 is turning KubeVirt's backup story from experimental into something operators can plan around, while DRA-based networking and CPU allocation move it closer to how Kubernetes now hands out hardware. Lower overhead is a side thread: virt-launcher-monitor was rewritten in C to use about 2 MiB. Based on the 1.9 cycle, which went rc.0 to rc.2 in four weeks, the final release is likely a few weeks out.
◆ Prediction
Expect at least one more 1.10 release candidate, then the final, with incremental backup as the headline beta feature.
Clair
2.5INFRA · APIS
Clair 4.10 RC can read SBOMs to match Java vulnerabilities.
◆ Current state
Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.
◆ Where it's heading
Since 4.8 Clair has moved from Red Hat's older OVAL data to VEX, and each release follows Red Hat's security data more closely. 4.10 adds SBOMs as an input, so Clair can match what an image's own manifest declares, not only what it finds on disk.
◆ Prediction
More 4.10 release candidates and then a final are likely; the long gap between releases suggests that could take weeks.
