Highlights

Buffer Overflow: 8 prior fixes. Scrutinize any change in this area.

src/ncp-spinel/SpinelNCPInstance.cpp: most-fixed (3 issues). Treat as high-risk during review.

5 high-severity fixes in this history; regressions here are high-impact.

Recurring patterns

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

Buffer Overflow: Multiple independent overflows in packet parsing and metric unpacking; one high-severity OOB read in TmfProxy:Stream and two medium overflows from length type mismatches.

Buffer Overflow: Global buffer overflow in fd_set_merge due to missing clamp on fd_count; direct evidence of unsafe fd_set copying.

Buffer Overflow: Buffer overflow in fd_set macros (FD_ISSET/FD_CLR) from out-of-range fd; bounds check added but the pattern suggests fd management is a recurring risk.
