Incus vs Clair: at a glance
What is Incus?
Incus 7.6 fixes 18 security issues, eight critical, and adds SR-IOV NIC live migration
Incus 7.6, released October 30, carries 18 security fixes, eight rated critical, many of them about restricted projects reaching the default project or the host, plus an authentication bypass through unverified client certificate chains. Its features aim at larger environments: live migration for VMs using SR-IOV NICs, multifd for VM live migration, cluster healing options, compression for block volumes, and OIDC opaque tokens. 7.5 before it added live migration between projects, cluster metrics and NVIDIA GPU cliques. The 7.0 LTS branch received a second patch, 7.0.2, with no described changes.
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.

Incus 7.6 fixes 18 security issues, eight critical, and adds SR-IOV NIC live migration
◆ Current state
Incus 7.6, released October 30, carries 18 security fixes, eight rated critical, many of them about restricted projects reaching the default project or the host, plus an authentication bypass through unverified client certificate chains. Its features aim at larger environments: live migration for VMs using SR-IOV NICs, multifd for VM live migration, cluster healing options, compression for block volumes, and OIDC opaque tokens. 7.5 before it added live migration between projects, cluster metrics and NVIDIA GPU cliques. The 7.0 LTS branch received a second patch, 7.0.2, with no described changes.
◆ Where it's heading
Live migration is still the through-line: 7.4 made it near-live for dependent disks, 7.5 took it across projects, and 7.6 extends it to VMs using SR-IOV NICs. The other thread is multi-tenancy under scrutiny. The size of the 7.6 security batch, with several critical items in project isolation, shows that restricted projects are now being tested as a real boundary, and the release adds a build and threat model for Anthropic's OSS Scanner.
◆ Prediction
Expect a 7.6.x patch or further security fixes, because the project-isolation findings cover a wide surface. The monthly feature cadence should continue with more live-migration throughput work, given multifd and the throughput improvements in this release.
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.
