CVE-2025-69652

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.

GNU Binutils hasta 2.46 readelf contiene una vulnerabilidad que conduce a una interrupción (SIGABRT) al procesar un binario ELF manipulado con información DWARF abbrev o de depuración malformada. Debido a una limpieza de estado incompleta en process_debug_info(), un estado debug_info_p inválido puede propagarse a las rutinas de análisis de atributos DWARF. Cuando ciertos atributos malformados resultan en una longitud de datos inesperada de cero, byte_get_little_endian() desencadena una interrupción fatal. No se observó evidencia de corrupción de memoria o ejecución de código; el impacto se limita a la denegación de servicio.
