CVE-2017-7277 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.39% chance of exploitation in the next 30 days.
