Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Integer Overflow: Unchecked capacity calculations during buffer reservations can lead to integer overflows, causing incorrect allocations, out-of-bounds memory writes, and undefined behavior. This is a recurring vulnerability type represented by CVE-2026-25541.
Memory Corruption: Underflows and incorrect offset calculations during resize or reservation operations have previously resulted in severe out-of-bounds pointer adjustments and direct memory corruption.
Memory Safety: Flawed synchronization of active bounds, incorrect pointer casting, and premature creation of exclusive references (causing aliasing violations) can lead to severe undefined behavior or double-free scenarios.
