# Checklist for submitter
- [x] Changes file added (`changes/45710-zorin-os-support`).
- [x] Input data is properly validated, `SELECT *` is avoided, SQL
injection is prevented (using placeholders for values in statements), JS
inline code is prevented especially for url redirects, and untrusted
data interpolated into shell scripts/commands is validated against shell
metacharacters.
- [x] Timeouts are implemented and retries are limited to avoid infinite
loops.
- [x] If paths of existing endpoints are modified without backwards
compatibility, checked the frontend/CLI for any necessary changes.
## Testing
- [x] Added/updated automated tests —
`server/vulnerabilities/oval/oval_platform_test.go` extended with Zorin
→ Ubuntu LTS mapping cases (16/17/18) plus an unknown-version case
(`Zorin OS 99` → `zorin_99`, which `IsSupported()` rejects).
- [x] QA'd all new/changed functionality manually — Zorin OS 17.0 and
18.1 hosts enrolled against a patched Fleet server, host details show
`platform=zorin`, software inventory populates, and OVAL CVE matching
produces results against the corresponding `ubuntu_2204` / `ubuntu_2404`
feeds.
## Database migrations
- N/A. No schema changes.
## New Fleet configuration settings
- N/A. No new settings.
## fleetd/orbit/Fleet Desktop
- N/A. Server + frontend only; no fleetd/orbit changes.

## Summary
Fleet previously logged `unrecognized platform` for Zorin OS hosts
(osquery reports `platform=zorin` from `/etc/os-release` `ID=zorin`).
The common workaround was running osquery with
`--force_platform=ubuntu`, which masquerades the host. This change adds
`zorin` as a first-class Linux platform alongside Ubuntu:
- **`server/fleet/hosts.go`** — register `zorin` in `HostLinuxOSs` and
`HostDebPackageOSs`
- **`server/datastore/mysql/linux_mdm.go`** — include Zorin in the Linux
disk-encryption summary query
- **`server/vulnerabilities/oval/oval_platform.go`** — map Zorin major
version to the underlying Ubuntu LTS OVAL feed (16 → 20.04, 17 → 22.04,
18 → 24.04). Unknown future versions fall through to an unsupported
`zorin_<major>` identifier so vulnerability scanning is skipped rather
than served stale data from an aging LTS feed.
- **frontend** — add `zorin` to `HOST_LINUX_PLATFORMS`, the
disk-encryption support list and type guard, the label platform
dropdown, and the icon mapping (Ubuntu icon, since no Zorin-specific
asset exists in the repo).
No new dependency, schema migration, or config setting. Reuses existing
Ubuntu OVAL feeds and the existing Ubuntu icon.

## Summary by CodeRabbit
* **New Features**
* Added Zorin OS as a supported Linux platform.
* Zorin hosts included in Linux disk-encryption summaries and treated as
disk-encryption capable.
* Zorin OS available as a selectable/filterable platform label and
considered DEB-install compatible.
* Vulnerability scanning enabled for Zorin 16→Ubuntu 20.04, 17→22.04,
18→24.04; unknown/future Zorin versions are marked unsupported and
skipped for CVE matching.
