What's new in 1.22.3

This is the 1.22.3 release of Rancher Desktop, an open source desktop application to bring Kubernetes and container management to macOS, Windows, and Linux. Installers - Windows - macOS x86_64 - macOS aarch64 - Linux install notes Release Notes for 1.22.3 Rancher Desktop 1.22.3 is a security-focused patch release. We strongly recommend upgrading. Security Fixes Container escape mitigation (CVE-2026-31431, CVE-2026-43284, CVE-2026-43500) Three recent Linux kernel exploits — copy.fail (CVE-2026-31431) and the two dirtyfrag variants (CVE-2026-43284, CVE-2026-43500) — let unprivileged processes gain a page-cache write primitive and tamper with files outside their normal reach. Inside Rancher Desktop, that means an attacker with code execution in any container could escape that scope and modify the rest of the VM. Each exploit needs a specific Linux kernel module loaded. Rancher Desktop now removes those modules, so the exploits have nothing to hook into.
