While we likely have to wait for macOS Ventura 13 to be released to the public in October (when new Macs will likely also be unveiled), there is a macOS Monterey 12.6 update available as of today. The update is the sixth major update to Monterey, and comes a few months after the release of macOS Monterey 12.5.
The Monterey 12.6 update can be downloaded to a compatible Mac via the Software Update section of System Preferences. Like all Mac updates, the macOS Monterey update is available free of charge.
macOS Monterey 12.6 addresses a number of kernel vulnerabilities, and brings fixes for issues with maps, iMovie, ATS, MediaLibrary, and PackageKit.
