Exploit públicoDisponiblePublicado en Exploit-DB

La implementación del coredump en el kernel de Linux en versiones anteriores a 5.0.10, no utiliza mecanismos de bloqueo u otros mecanismos para evitar cambios en el layout de vma o en los flags vma mientras se ejecuta, lo que permite a los usuarios locales obtener información sensible, causar una denegación de servicio o posiblemente tener otro impacto no especificado al activar una condición de carrera con llamadas mmget_not_zero o get_task_mm. Esto está relacionado con fs/userfaultfd.c, mm/mmap.c, fs/proc/task_mmu.c, y drivers/infiniband/core/uverbs_main.c

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
