GHSA-wwxp-hxh6-8gf8 — Vulnerability in binary_vec_io — Advisory...

HIGH

binary_vec_io access memory out-of-bounds in binary_read_to_ref and binary_write_from_ref

Published October 22, 2025Updated October 28, 2025Source: osv

Summary

Safe functions accept a single `&T` or `&mut T` but multiply by `n` to create slices extending beyond allocated memory when `n > 1`. These functions use `from_raw_parts` to create slices larger than the underlying allocation, violating memory safety. The binary_vec_io repository is archived and unmaintained.
