The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the Linux kernel before 4.6.3 allows local users to gain privileges or cause a denial of service (stack memory consumption) via vectors involving crafted mmap calls for /proc pathnames, leading to recursive pagefault handling.

CVE-2016-1583 [HIGH] CWE-121 kernel: Stack overflow via ecryptfs and /proc/$pid/environ
kernel: Stack overflow via ecryptfs and /proc/$pid/environ
The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the Linux kernel before 4.6.3 allows local users to gain privileges or cause a denial of service (stack memory consumption) via vectors involving crafted mmap calls for /proc pathnames, leading to recursive pagefault handling.
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.

There are legitimate reasons to disallow mmap on certain files, notably
in sysfs or procfs. We shouldn't emulate mmap support on file systems
that don't offer support natively.

CVE-2016-1583 kernel: Stack overflow via ecryptfs and /proc/$pid/environ
The ecryptfs mechanism can be used to mmap files that normally wouldn't be mmapable, especially /proc/$pid/{mem,environ,cmdline} files. An attacker could chain e.g. /proc/$pid/environ mappings where process 1 has /proc/2/environ mapped into its environment area, process 2 has /proc/3/environ mapped into its environment area and so on, that can lead to kernel stack overflow.
This can be chained together into a stack overflow and an attacker can escalate their privileges.
