CVE-2026-6846
Full vulnerability record from the local CVENow database.
Description
A flaw was found in binutils. A heap-buffer-overflow vulnerability exists when processing a specially crafted XCOFF (Extended Common Object File Format) object file during linking. A local attacker could trick a user into processing this malicious file, which could lead to arbitrary code execution, allowing the attacker to run unauthorized commands, or cause a denial of service, making the system unavailable.

Existe una vulnerabilidad de desbordamiento de búfer de pila (heap-buffer-overflow) al procesar un archivo objeto XCOFF (Extended Common Object File Format) especialmente manipulado durante la vinculación. Un atacante local podría engañar a un usuario para que procese este archivo malicioso, lo que podría llevar a la ejecución de código arbitrario, permitiendo al atacante ejecutar comandos no autorizados, o causar una denegación de servicio, dejando el sistema no disponible."
