Oracle Linux: CVE-2017-17712: ELSA-2018-4025: Unbreakable Enterprise kernel security update (IMPORTANT)

The raw_sendmsg() function in net/ipv4/raw.c in the Linux kernel through 4.14.6 has a race condition in inet->hdrincl that leads to uninitialized stack pointer usage; this allows a local user to execute code and gain privileges.
A flaw was found in the Linux kernel's implementation of raw_sendmsg allowing a local attacker to panic the kernel or possibly leak kernel addresses. A local attacker, with the privilege of creating raw sockets, can abuse a possible race condition when setting the socket option to allow the kernel to automatically create ip header values and thus potentially escalate their privileges.
