AnalysisAIv1 – Sep 15, 2026

A NULL pointer dereference in GNU Binutils 2.47 lets a locally-supplied, malformed ELF object crash BFD-based tools such as ld, objdump or readelf when they parse the crafted symbol tables. Only availability is affected — the process dies with a segmentation fault and there is no confidentiality or integrity impact. Publicly available exploit code exists (a PoC is published in a GitHub repository referenced from the Sourceware bug report), but there is no CISA KEV listing and no vendor patch at the time of analysis, since the project has reportedly not yet responded to the bug report.

DescriptionCVE.org

A weakness has been identified in GNU Binutils 2.47. This impacts the function elf_link_add_object_symbols of the file bfd/elflink.c. Executing a manipulation can lead to null pointer dereference. The attack needs to be launched locally. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through a bug report but has not responded yet.

Attack Technique

A null pointer dereference occurs when a program attempts to access memory through a pointer that has been set to NULL (address 0x0).

Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
