Descriptions

The ethtool_get_rxnfc function in net/core/ethtool.c in the Linux kernel before 2.6.36 does not initialize a certain block of heap memory, which allows local users to obtain potentially sensitive information via an ETHTOOL_GRXCLSRLALL ethtool command with a large info.rule_cnt value, a different vulnerability than CVE-2010-2478.

La función ethtool_get_rxnfc en net/core/ethtool.c en el kernel Linux, en versiones anteriores a la 2.6.36 no inicializa un cierto bloque de memoria dinámica, lo que permite a usuarios locales obtener información potencialmente sensible a través de un comando ethtool ETHTOOL_GRXCLSRLALL con un valor info.rule_cnt de gran tamaño, una vulnerabilidad diferente a CVE-2010-2478.
