StaamlCorp operates a single-portfolio licensing program for temporal security discontinuities — a class of vulnerability where cached executable content persists across security policy transitions. Validated by Apple. Applicable across platforms. Licensed on fair and reasonable terms.
In 2025, founder Stanley Lee Linton identified a previously undocumented class of vulnerability — designated LDB-01 — in which cached executable content persisted across security policy transitions. Apple reproduced and remediated their instance; StaamlCorp patented the generalized framework.
Cached WebAssembly modules, JavaScript blobs, and Service Worker scripts cached during standard operation remained executable after iOS Lockdown Mode activation — one concrete instance of cached-executable persistence across a policy transition.
Reported to Apple Security. Apple reproduced the vulnerability, assigned CVE reference webkit-294380, and shipped a fix in iOS 26 and iPadOS 26. Apple’s response acknowledged the work as security-beneficial research warranting recognition.
The underlying class — cached executables surviving a security policy change — appears wherever those two conditions coexist. StaamlCorp's patent claims cover the generalized detection-and-mitigation framework, not any single vendor's product.
StaamlCorp's utility patent covers the complete, platform-independent framework for detecting and mitigating cached executable persistence across security policy transitions.
Title: System and Method for Mitigating Cached Executable Persistence Across Security Policy Transitions
Status: Pending — Track One Prioritized Examination · Claims subject to amendment
Claims: 30 total (4 independent, 26 dependent)
Coverage: 7+ content types, 6+ cache locations, 7+ platforms, all policy transition types
The pending claims describe a complete loop: detecting a security policy transition, evaluating cached executable content under the new policy, and mitigating non-compliant items with an audit trail.
The underlying vulnerability class was independently reproduced and remediated by Apple Inc. — CVE webkit-294380, fixed in iOS 26 and iPadOS 26.
Patent claims cover iOS, Android, Windows, macOS, Linux, embedded systems, autonomous AI agents, browsers, enterprise MDM, and cloud/container environments.
Research, analysis, and technical deep-dives from our team.
Every modern computing device relies on cached executable content and supports multiple security states. The vulnerability class exists at the intersection of these two realities.
How Lockdown Mode's threat model treated cached executables, what the LDB-01 finding showed, and what it suggests about cache-layer assumptions in adjacent security architectures.
The most consequential instantiations of temporal security discontinuity may not involve browsers at all. They will involve artificial intelligence.
