What is CVE-2025-69652?
CVE-2025-69652 is a medium-severity denial of service vulnerability in Gnu Binutils, published on 6 Mar 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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.
Weakness: CWE-460
