CVE-2025-69646

21
FAUCET Score

CVE-2025-69646 describes a denial-of-service vulnerability in Binutils objdump, specifically affecting version 2.44. A local attacker can exploit a logic error in handling malformed DWARF debug_rnglists data within a crafted binary, causing objdump to enter an infinite loop of warning messages. This leads to excessive CPU and I/O usage, preventing analysis completion and effectively denying service. While no CVSS score is available, the attack requires local access and a specially crafted file, limiting its complexity. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.

Vendor Advisories (1)

microsoft2026-Mar/CVE-2025-69646Moderate

Binutils objdump contains a denial-of-service vulnerability when processing a crafted binary with malformed DWARF debug_rnglists data. A logic error in the handling of the debug_rnglists header can cause objdump to repeatedly print the same warning message and fail to terminate, resulting in an unbounded logging loop until the process is interrupted. The issue was observed in binutils 2.44. A local attacker can exploit this vulnerability by supplying a malicious input file, leading to excessive CPU and I/O usage and preventing completion of the objdump analysis.
