Kata Containers vs Velociraptor: at a glance
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.
What is Velociraptor?
Velociraptor's recent releases are mostly about patching CVEs.
Velociraptor 0.77.3 shipped on October 5 as a bug fix and CVE release; it also adds an artifact that uploads server results to Azure Monitor and trims the columns emitted by the backup artifacts. 0.77.2 and a 0.76.7 backport in September and August were CVE fixes. The 0.77.1 feature release landed in June, but its notes in the feed only link out.

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.
Velociraptor
0.0INFRA · APIS
Velociraptor's recent releases are mostly about patching CVEs.
◆ Current state
Velociraptor 0.77.3 shipped on October 5 as a bug fix and CVE release; it also adds an artifact that uploads server results to Azure Monitor and trims the columns emitted by the backup artifacts. 0.77.2 and a 0.76.7 backport in September and August were CVE fixes. The 0.77.1 feature release landed in June, but its notes in the feed only link out.
◆ Where it's heading
Since June the project has been in security mode, fixing CVEs on the current line and backporting to the previous one. Feature work shows up as new artifacts, here an Azure Monitor export, which keeps Velociraptor feeding results into the logging tools teams already use.
◆ Prediction
Expect further 0.77 patch releases and possibly another backport if new CVEs are published; the timing of a 0.78 feature release is not signaled here.
