CVE-2016-1583

Priority
Description
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.
Ubuntu-Description
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.
