CVE-2014-2568

Estado: ModificadaBaja (2.9)—

Vulnerabilidad de uso después de liberación en la función nfqnl_zcopy en net/netfilter/nfnetlink_queue_core.c en el kernel de Linux hasta 3.13.6 permite a atacantes obtener información sensible de la memoria del kernel mediante el aprovechamiento de la ausencia de cierta operación huérfana. NOTA: el código afectado fue trasladado a la función skb_zerocopy en net/core/skbuff.c antes de que la vulnerabilidad fue anunciada.
