Gloo Gateway vs Kata Containers: at a glance
What is Gloo Gateway?
Gloo Gateway's October batch fixes proxies that silently kept stale endpoints.
Gloo Gateway still maintains 1.19, 1.20 and 1.21 in parallel and releases them in same-day batches. The 2026-10-21 batch fixes a bug where a placeholder EDS assignment carried the wrong cluster name, so a proxy received an update it could not match, kept its old endpoints and never recovered. Each line also moved to Go 1.26.10; 1.21 additionally upgraded kin-openapi.
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.

Gloo Gateway
5.0INFRA · APIS
Gloo Gateway's October batch fixes proxies that silently kept stale endpoints.
◆ Current state
Gloo Gateway still maintains 1.19, 1.20 and 1.21 in parallel and releases them in same-day batches. The 2026-10-21 batch fixes a bug where a placeholder EDS assignment carried the wrong cluster name, so a proxy received an update it could not match, kept its old endpoints and never recovered. Each line also moved to Go 1.26.10; 1.21 additionally upgraded kin-openapi.
◆ Where it's heading
Releases remain maintenance: Go and Kubernetes bumps on a weekly rhythm, with an occasional real bug fix shipped to every line at once. The 1.18 line no longer appears in the October batches. No new features are visible.
◆ Prediction
Expect further same-day dependency batches across the three lines; the entries show no feature release coming.
Kata Containers
5.0INFRA · APIS
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.
