Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Sandbox Escape: Status-code propagation failures and typo-induced pointer comparisons in Windows process hardening can allow untrusted processes to bypass memory replacement and signature validation, leading to sandbox escapes.

Host System Hijack from Guest: Insufficent dynamic buffer size checks when querying compressed texture formats in SharedOpenGL permit guest-to-host heap buffer overflows and hypervisor escape.

Access Control Bypass: Ignoring file-open handles (comparing INVALID_HANDLE_VALUE to NULL) and shadowed return-code variables in hardened path validation routines can permit untrusted or unsigned libraries to execute.
