implementation in the Linux kernel did not properly reference count file
descriptors, leading to a use-after-free. A local unprivileged attacker
could use this to gain administrative privileges. (CVE-2016-4557<\/a>)<\/p>\n
did not properly validate USB device descriptors. An attacker with physical
access could use this to cause a denial of service (system crash).
(CVE-2016-2184<\/a>)<\/p>\n
Linux kernel did not properly validate USB device descriptors. An attacker
with physical access could use this to cause a denial of service (system
crash). (CVE-2016-2185<\/a>)<\/p>\n
kernel did not properly validate USB device descriptors. An attacker with
physical access could use this to cause a denial of service (system crash).
(CVE-2016-2186<\/a>)<\/p>\n
Linux kernel did not properly validate USB device descriptors. An attacker
with physical access could use this to cause a denial of service (system
crash). (CVE-2016-2188<\/a>)<\/p>\n
MCT USB RS232 Converter device driver in the Linux kernel did not properly
validate USB device descriptors. An attacker with physical access could use
this to cause a denial of service (system crash). (CVE-2016-3136<\/a>)<\/p>\n
Cypress M8 USB device driver in the Linux kernel did not properly validate
USB device descriptors. An attacker with physical access could use this to
cause a denial of service (system crash). (CVE-2016-3137<\/a>)<\/p>\n
USB abstract device control driver for modems and ISDN adapters did not
validate endpoint descriptors. An attacker with physical access could use
this to cause a denial of service (system crash). (CVE-2016-3138<\/a>)<\/p>\n
Linux kernel's USB driver for Digi AccelePort serial converters did not
properly validate USB device descriptors. An attacker with physical access
could use this to cause a denial of service (system crash). (CVE-2016-3140<\/a>)<\/p>\n
perform the destruction of inet device objects properly. An attacker in a
guest OS could use this to cause a denial of service (networking outage) in
the host OS. (CVE-2016-3156<\/a>)<\/p>\n
switch IOPL on 64-bit PV Xen guests. An attacker in a guest OS could use
this to cause a denial of service (guest OS crash), gain privileges, or
obtain sensitive information. (CVE-2016-3157<\/a>)<\/p>\n
improperly disable Address Space Layout Randomization (ASLR) for x86
processes running in 32 bit mode if stack-consumption resource limits were
disabled. A local attacker could use this to make it easier to exploit an
existing vulnerability in a setuid\/setgid program. (CVE-2016-3672<\/a>)<\/p>\n
Control Unit devices did not properly validate the device's interfaces. An
attacker with physical access could use this to cause a denial of service
(system crash). (CVE-2016-3689<\/a>)<\/p>\n
in the Linux kernel did not cancel work events queued if a later error
occurred, resulting in a use-after-free. An attacker with physical access
could use this to cause a denial of service (system crash). (CVE-2016-3951<\/a>)<\/p>\n

attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2016-3955<\/a>)<\/p>\nUpdate instructions<\/h3>\n

been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.<\/p>\nReferences<\/h3>\n
