Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The sized-chunks crate for Rust, versions before 0.6.3, does not check the array size when a Chunk is constructed with pair(). The source gives few details on how an attacker would reach this or what impact it has. Upgrade sized-chunks to version 0.6.3 or later.

Written 8 Nov 2026.
