kernel is vulnerable to information disclosure. A flaw was found in the tcf_act_police_dump() function in the Linux kernel network traffic policing implementation. A data structure in tcf_act_police_dump() was not initialized properly before being copied to user-space. A local, unprivileged user could use this flaw to cause an information leak.
