CVE-2017-6074

Upstream information

CVE-2017-6074 at MITRE

Description

The dccp_rcv_state_process function in net/dccp/input.c in the Linux kernel through 4.9.11 mishandles DCCP_PKT_REQUEST packet data structures in the LISTEN state, which allows local users to obtain root privileges or cause a denial of service (double free) via an application that makes an IPV6_RECVPKTINFO setsockopt system call.

Note from the SUSE Security Team

This issue does not affect SUSE Linux Enterprise 12, as the DCCP network protocol is not built in. This issue does affect only the -extra unsupported kernel flavor in SUSE Linux Enterprise 11. Also, an active DCCP socket connection is likely needed to exploit this problem.
