Another Linux Kernel Vulnerability Leading To Local Root From Unprivileged Processes
CVE-2017-6074 was made public today as a DCCP double-free vulnerability that could allow for kernel code execution from an unprivileged process.
This local root vulnerability is present in Linux kernel releases going back at least to 2006 but potentially to 2005 when the code was first introduced. It affects kernel builds with CONFIG_IP_DCCP, which is the case for many distribution kernels. Checking my Fedora 25 kernel right now, it's enabled. DCCP in this context is short for the Datagram Congestion Control Protocol.
The vulnerability was fixed in Linux Git last week.
