Several vulnerabilities have been
discovered in the Linux kernel that may lead to a privilege escalation, denial of
service or information leaks.
CVE-2015-7515,
CVE-2016-2184,
CVE-2016-2185,
CVE-2016-2186,
CVE-2016-2187,

CVE-2016-3137,
CVE-2016-3138,
CVE-2016-3140
Ralf Spenneberg of OpenSource Security reported that various USB
drivers do not sufficiently validate USB descriptors. This
allowed a physically present user with a specially designed USB
device to cause a denial of service (crash).
CVE-2016-0821Solar Designer noted that the list poisoning
feature, intended
to mitigate the effects of bugs in list manipulation in the
kernel, used poison values within the range of virtual addresses
that can be allocated by user processes.
CVE-2016-1237
David Sinquin discovered that nfsd does not check permissions when
setting ACLs, allowing users to grant themselves permissions to a
file by setting the ACL.
Description truncated. Please see the references for more information.

linux on Debian Linux
Solution:
For the stable distribution (jessie),
these problems have been fixed in version 3.16.7-ckt25-2+deb8u2.
