Published Mar 6, 2026CWE-476EPSS 0.24%

Overview

CVE-2025-69651 is a medium-severity vulnerability. It was published on March 6, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

GNU Binutils thru 2.46 readelf contains a vulnerability that leads to an invalid pointer free when processing a crafted ELF binary with malformed relocation or symbol data. If dump_relocations returns early due to parsing errors, the internal all_relocations array may remain partially uninitialized. Later, process_got_section_contents() may attempt to free an invalid r_symbol pointer, triggering memory corruption checks in glibc and causing the program to terminate with SIGABRT. No evidence of further memory corruption or code execution was observed; the impact is limited to denial of service. NOTE: this is disputed by third parties because the observed behavior occurred only in pre-release code and did not affect any tagged version.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
