What is FOSSA CLI?

fossa-cli's feed jumps from 3.17 to 3.20, with clearer container scan errors.

The newest entry, v3.20.10 (2026-10-31), makes container analysis report the registry error when an image layer fails to download instead of an internal threading error, and adds per-phase timing to analysis telemetry. The feed has no entries between 3.17.17 in August and 3.20.10, so the 3.18 to 3.20 releases are not visible here.

What is Kata Containers?

Kata Containers 4.3 fixes a guest-to-host escape and tightens annotation handling.

Kata Containers ships monthly, and 4.3.0 (October 21) carries two security fixes: a permissive annotation allowlist that could cause unintended host and guest changes (CVSS 7.9, existing installs need a config review) and out-of-bounds access in Dragonball virtio drivers that allowed guest-to-host escape (CVSS 6.4). The same release restricts containerd pod annotations, bumps the guest kernel to 6.18.52 and ships more NVIDIA GPU runtime components. 4.3.1 followed the same day with eMudhra certificate exclusion.

fossa-cli's feed jumps from 3.17 to 3.20, with clearer container scan errors.

◆ Current state

The newest entry, v3.20.10 (2026-10-31), makes container analysis report the registry error when an image layer fails to download instead of an internal threading error, and adds per-phase timing to analysis telemetry. The feed has no entries between 3.17.17 in August and 3.20.10, so the 3.18 to 3.20 releases are not visible here.

◆ Where it's heading

The visible releases are ecosystem-by-ecosystem accuracy fixes (npm, pnpm, sbt, Conan, dpkg) and operational adjustments such as a longer default timeout. With three minor versions missing from the feed, any larger changes in that span can't be assessed from these entries.

◆ Prediction

Expect more per-ecosystem resolution fixes and patch releases; the gap in the feed makes a more specific prediction unreliable.

5.0

Kata Containers 4.3 fixes a guest-to-host escape and tightens annotation handling.

◆ Current state

Kata Containers ships monthly, and 4.3.0 (October 21) carries two security fixes: a permissive annotation allowlist that could cause unintended host and guest changes (CVSS 7.9, existing installs need a config review) and out-of-bounds access in Dragonball virtio drivers that allowed guest-to-host escape (CVSS 6.4). The same release restricts containerd pod annotations, bumps the guest kernel to 6.18.52 and ships more NVIDIA GPU runtime components. 4.3.1 followed the same day with eMudhra certificate exclusion.

◆ Where it's heading

Since the Rust runtime became the default in 4.0, releases have gone to GPU packaging, kata-deploy's move to a job-based deployment mode and policy hardening in genpolicy. 4.2.0 moved the rootfs to Ubuntu 26.04 and passed QEMU block and VFIO devices by file descriptor; 4.3.0 continues with rootless VMM provisioning and guest-pulled image verification.

◆ Prediction

4.4.0 should land around November 17, given the documented target of the first Tuesday after the 15th. Expect more NVIDIA GPU packaging work, a thread in 4.1, 4.2 and 4.3.
