CVE-2017-7277

Published: 28 March 2017

The TCP stack in the Linux kernel through 4.10.6 mishandles the SCM_TIMESTAMPING_OPT_STATS feature, which allows local users to obtain sensitive information from the kernel's internal socket data structures or cause a denial of service (out-of-bounds read) via crafted system calls, related to net/core/skbuff.c and net/socket.c.

From the Ubuntu security team

JongHwan Kim discovered an out-of-bounds read in the TCP stack of the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or leak sensitive information.
