NVD description

A flaw was found in the GNU Binutils (Binary Utilities) linker. This vulnerability, a heap-buffer-overflow read (CWE-125), occurs when the linker processes a specially crafted 32-bit XCOFF (Extended Common Object File Format) object file. An attacker could exploit this by providing a malicious file, leading to an out-of-bounds read of memory. This can result in information disclosure, potentially revealing sensitive heap data, and a Denial of Service (DoS) due to the linker crashing.

    The 2 with CVEs: a heap overflow (CVE-2026-6846) and an OOB read (CVE-2026-15003) in XCOFF symbol loading. The 2 without: a symbol index used with no bound check, and a csect index tested against a byte offset, not a count. Same function. Same class. No CVE. https://t.co/AEJB1pjIqJ
