Description OSIDB Bzimport 2026-03-02 14:16:00 UTC 
Summary: A separate heap-based buffer overflow (Out-of-Bounds Read) was found in GNU Binutils (bfd linker) in bfd/xcofflink.c. This issue occurs in xcoff_link_add_symbols (approx line 2282) where r_symndx is used to index symbol hashes without sufficient bounds checking.
Requirements to exploit: An attacker needs to trick a user into running the ld linker against a specially crafted malicious XCOFF object file.
