CVE-2014-0131

Vulnerabilidad de uso después de liberación en la función skb_segment en net/core/skbuff.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.

Sasha Levin reported a flaw in the Linux kernel's point-to-point protocol (PPP) when used with the Layer Two Tunneling Protocol (L2TP). A local user could exploit this flaw to gain administrative privileges. Michael S. Tsirkin discovered an information leak in the Linux kernel's segmentation of skbs when using the zerocopy feature of vhost-net. A local attacker could exploit this flaw to gain potentially sensitive information from kernel memory. Various other issues were also addressed.
