Received Received - Intake
Denial of Service in GNU Binutils readelf via Malformed DWARF Parsing

Publication date: 2026-03-06

Last updated on: 2026-03-11

Assigner: MITRE

Description
GNU Binutils thru 2.46 readelf contains a vulnerability that leads to an abort (SIGABRT) when processing a crafted ELF binary with malformed DWARF abbrev or debug information. Due to incomplete state cleanup in process_debug_info(), an invalid debug_info_p state may propagate into DWARF attribute parsing routines. When certain malformed attributes result in an unexpected data length of zero, byte_get_little_endian() triggers a fatal abort. No evidence of memory corruption or code execution was observed; the impact is limited to denial of service.

Executive Summary

This vulnerability exists in GNU Binutils through version 2.46, specifically in the readelf tool. It occurs when readelf processes a specially crafted ELF binary containing malformed DWARF abbreviation or debug information. Due to incomplete cleanup of internal state in the function process_debug_info(), an invalid debug_info_p state can propagate into DWARF attribute parsing routines. When certain malformed attributes cause an unexpected data length of zero, the function byte_get_little_endian() triggers a fatal abort (SIGABRT), causing the program to terminate unexpectedly.

Impact Analysis

The impact of this vulnerability is limited to denial of service. When exploited, it causes the readelf tool to abort unexpectedly, which could disrupt processes relying on readelf to analyze ELF binaries. There is no evidence that this vulnerability leads to memory corruption or code execution.
