CVE-2018-10689

Estado: ModificadaMedia (5.5)—

blktrace (también conocido como Block IO Tracing) 1.2.0, tal y como se emplea en el kernel de Linux y Android, tiene un desbordamiento de búfer en la función dev_map_read en btt/devmap.c debido a que los arrays device y devno son demasiado pequeños, tal y como queda demostrado con una liberación no válida al emplear el programa btt con un archivo manipulado.

CVSS

Probabilidad de explotación (EPSS)

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).
