Recurring patterns

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

Memory Corruption: Inconsistencies between the internal memory layout of custom objects (NYTUPLELIKE) and CPython's allocator expectations (specifically regarding fields like ob_hash in Python 3.14) can lead to out-of-bounds writes, heap corruption, or misaligned memory access. Developers must carefully track changes in CPython's PyObject definitions.
