CVE-2009-1961

Estado: ModificadaMedia (4.7)—💥 Exploit

El código de doble bloqueo del inodo de fs/ocfs2/file.c del kernel de Linux v2.6.30 anterior a v2.6.30-rc3, v2.6.27 anterior a v2.6.27.24, v2.6.29 anterior a v2.6.29.4 y puede que otras versiones anteriores a v2.6.19; permite a usuarios locales provocar una denegación de servicio (prevención de creación y borrado de ficheros) a través de una serie de llamadas al sistema anidadas que provocan un bloqueo mutuo -deadlock- entre las funciones generic_file_splice_write, splice_from_pipe y ocfs2_file_splice_write.

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).

💥 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.
