Vulnerabilidad alta en código de volcado de núcleo ELF permite escritura de memoria fuera de límites
Una vulnerabilidad en el procesamiento de volcados de núcleo ELF (CVE-2026-58088, CVSS 7.4) permite que procesos no privilegiados que compartan espacio de direcciones mediante rfork(2) causen desbordamientos de búfer al mutar mapas de memoria entre dos pasadas de iteración. Afecta principalmente a sistemas Unix/Linux en servidores y estaciones de trabajo en LATAM donde se ejecutan aplicaciones con multiprocessing.
