computer weakness note 18032

Linux kernel: information disclosure via openvswitch

Synthesis of the vulnerability

A local attacker can read a memory fragment of the Linux kernel via openvswitch, in order to obtain sensitive information.
Severity: 1/4.
Creation date: 05/10/2015.
Identifiers: VIGILANCE-VUL-18032.
Full Vigil@nce bulletin... (Free trial)

Description of the vulnerability

The Linux kernel implements Open vSwitch, a virtual switch.

However, the ovs_flow_alloc() function of the net/openvswitch/flow_table.c file does not initialize a memory area before returning it to the user.

A local attacker can therefore read a memory fragment of the Linux kernel via openvswitch, in order to obtain sensitive information.
