1) Resource exhaustion (CVE-ID: CVE-2016-1583)
CWE-ID: CWE-400 - Resource exhaustion

The vulnerability allows a local attacker to cause DoS condition and gain elevated privileges on the target system.
The weakness exists in the ecryptfs_privileged_open function in fs/ecryptfs/kthread.c due to stack memory consumption. A local attacker can cause the service to crash and gain elevated privileges via vectors involving crafted mmap calls for /proc pathnames, leading to recursive pagefault handling.
