Recurring patterns

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

Denial of Service: Truncated pointer registers during assembly dispatch under specific Clang compiler versions (Clang 7 and 8) can lead to segmentation faults and denial of service. Developers must ensure register widths are correctly cast and maintained across different target architectures and compilers.

Missing Security Mitigation: Missing non-executable stack markers in assembly source files or build configurations can allow arbitrary code execution from the stack if a memory corruption vulnerability is exploited on Unix systems.
