CVE-2010-3477

Estado: ModificadaBaja (2.1)—

La función tcf_act_police_dump en net/sched/act_police.c del kernel Linux anterior a la v2.6.36-rc4 no inicializa apropiadamente ciertos miembros de estructura, lo que permite a usuarios locales obtener información potencialmente sensible de la memoria del kernel a través de vectores que involucran una operación de volcado (dump). NOTA: esta vulnerabilidad existe como consecuencia de una solución incompleta para CVE-2010-2942.
