CVE-2026-15003 – Binutils: gnu binutils: heap-buffer-overflow in linker leads to information disclosure and denial of service

CVE ID :CVE-2026-15003

Published : July 27, 2026, 1:22 p.m. | 33 minutes ago

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.

Severity: 5.6 | MEDIUM
