binutils: A flaw was found in the GNU Binutils (Binary Utilities) linker
CVE-2026-15003 is fixed in binutils on 1 platform by DEBIAN-CVE-2026-15003 (version 2.47-1), released August 1, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
