Red Hat Security Advisory 2017-2760-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: It was found that stacking a file system over procfs in the Linux kernel could lead to a kernel stack overflow due to deep nesting, as demonstrated by mounting ecryptfs over procfs and creating a recursion by mapping /proc/environ. An unprivileged, local user could potentially use this flaw to escalate their privileges on the system.

Security Fix: A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.
