CVE-2025-69646
Description
A flaw was found in binutils. A local attacker can exploit this vulnerability by supplying a malicious input file containing malformed DWARF debug_rnglists data. This can cause the objdump tool to enter an unbounded logging loop, leading to excessive CPU and I/O usage and preventing analysis completion. This issue results in a Denial of Service (DoS).
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
