Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Integer Overflow: Additive arithmetic in buffer size and index validation can overflow, leading to bypassed bounds checks and downstream out-of-bounds memory operations. This was historically mitigated by restructuring comparisons to avoid additive overflow.
Out-of-bounds Read/Write: Wrapping raw memory addresses without resetting internal tracking variables like wrapAdjustment can cause incorrect address calculation offsets, triggering unsafe memory access outside the allocated buffer boundaries.
