Overview: Root Lock by HeartSuite runs custom-built Linux kernels (5.19 legacy and 6.18 primary LTS) that remove the subsystems attackers use to bypass security controls, rather than patching around them. This section covers buyer evaluation, support policy, compatibility, scanner hygiene, and reproducible evidence.
Start here if you are evaluating the HS kernel for a regulated or enterprise fleet:
/advisories/ (CONFIG-gate SBOM, OSV with 279 entries, CycloneDX SBOM for hs-v1.6.4-kernel-6.18.9); roadmap for GPG/cosign signing and OVAL.Reading guide: Several pages name Red Hat Enterprise Linux (RHEL), RHSA advisories, and OVAL feeds as familiar anchors for procurement and vulnerability-management teams — the same errata-first discipline applies on Rocky, AlmaLinux, Ubuntu LTS, Debian, and SUSE. HeartSuite is not a RHEL-only product; the Distro Compatibility Matrix lists validated bases across RPM and Debian families.
Every measured number derives from the open-source kernel-hardening-checker tool applied identically to HeartSuite and reference kernels. No estimates. Raw evidence files and config SHA-256 hashes are included so any qualified team can verify independently.
Plain-language comparison of Root Lock by HeartSuite HS kernel hardening against industry alternatives — 6.18.9 primary commercial baseline; measured tables reference the published 5.19.6 legacy stream until 6.18.9 evidence ships.
Practical guidance for CISOs, procurement teams, and security architects evaluating the custom-built kernel used by Root Lock by HeartSuite — why it exists, how vendor risk is owned, deployment and fleet operations, Secure Boot status, compatibility, supply chain, recovery paths, evidence for auditors, and honest limitations including alternatives for strict no-custom-kernel policies.
Which Linux distributions Root Lock by HeartSuite supports for the HS kernel — validation tiers, boot paths, RPM and Debian family notes, workload fit, and how to report compatibility issues.
HeartSuite kernel support policy for HS kernel streams, LTS strategy, patch targets, update delivery, version-string semantics, 5.19 deprecation, and boundaries versus distribution-vendor maintenance models.
How enterprise Linux security teams verify Root Lock by HeartSuite kernel CVE status without false positives from upstream version comparison — correct workflow, status categories, scanner configuration, maintenance-kernel exceptions, and audit evidence.
HeartSuite HS kernel supply-chain artefacts — SHA-256 bundle integrity, bundle manifest fields, reproducible config hashes, published machine-readable advisory feeds (CONFIG-gate SBOM, OSV, CycloneDX), and roadmap for GPG/cosign signing and OVAL.
Publication status of HS kernel hardening evidence — 5.19.6 legacy stream (published) and 6.18.9 primary commercial baseline (in progress).
Comparison matrix structure for Root Lock by HeartSuite kernel 6.18.9 (HeartSuite v1.6.4 commercial baseline). Measured checker scores and config SHA-256 pending publication.
Objective comparison of Root Lock by HeartSuite 5.19.6 kernel configuration against industry hardened kernels and standard references, using kernel-hardening-checker (commit b9b83a0).
Technical assessment of Root Lock by HeartSuite HS kernel hardening posture for security auditors and red teams — 6.18.9 primary commercial baseline; measured scores and reproduction commands reference the published 5.19.6 legacy stream until 6.18.9 evidence ships.
Comparison of Root Lock by HeartSuite’s enforcement model against SELinux, AppArmor, and TOMOYO — focused on bypass-primitive resistance and purpose-fit for containment deployments.
