CVE-2026-4647

medium

A flaw was found in the GNU Binutils BFD library, a widely used component for handling binary files such as object files and executables.

Vendor / product: Gnu — binutils

A flaw was found in the GNU Binutils BFD library, a widely used component for handling binary files such as object files and executables. The issue occurs when processing specially crafted XCOFF object files, where a relocation type value is not properly validated before being used. This can cause the program to read memory outside of intended bounds. As a result, affected tools may crash or expose unintended memory contents, leading to denial-of-service or limited information disclosure risks.
