CVE-2016-1583
Published: 08 June 2016
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.
From the Ubuntu security team
Jann Horn discovered that eCryptfs improperly attempted to use the mmap() handler of a lower filesystem that did not implement one, causing a recursive page fault to occur. A local unprivileged attacker could use to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges.
