device. A physically proximate attacker could use this to cause a denial of
service (system crash). (CVE-2018-19985)

Zhipeng Xie discovered that an infinite loop could be triggered in the CFS
Linux kernel process scheduler. A local attacker could possibly use this to
cause a denial of service. (CVE-2018-20784)

It was discovered that the Intel Wi-Fi device driver in the Linux kernel did
not properly validate certain Tunneled Direct Link Setup (TDLS). A
physically proximate attacker could use this to cause a denial of service
(Wi-Fi disconnect). (CVE-2019-0136)

devices. (CVE-2019-10638)

Amit Klein and Benny Pinkas discovered that the location of kernel
addresses could be exposed by the implementation of connection-less network
protocols in the Linux kernel. A remote attacker could possibly use this to
assist in the exploitation of another vulnerability in the Linux kernel.
(CVE-2019-10639)

It was discovered that an integer overflow existed in the Linux kernel when
reference counting pages, leading to potential use-after-free issues. A
local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2019-11487)

Jann Horn discovered that a race condition existed in the Linux kernel when
performing core dumps. A local attacker could use this to cause a denial of
service (system crash) or expose sensitive information. (CVE-2019-11599)

It was discovered that a null pointer dereference vulnerability existed in
the LSI Logic MegaRAID driver in the Linux kernel. A local attacker could
use this to cause a denial of service (system crash). (CVE-2019-11810)

It was discovered that the GTCO tablet input driver in the Linux kernel did
not properly bounds check the initial HID report sent by the device. A
physically proximate attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2019-13631)

Praveen Pandey discovered that the Linux kernel did not properly validate
sent signals in some situations on PowerPC systems with transactional
memory disabled. A local attacker could use this to cause a denial of
service. (CVE-2019-13648)

It was discovered that the floppy driver in the Linux kernel did not
properly validate meta data, leading to a buffer overread. A local attacker
could use this to cause a denial of service (system crash).
(CVE-2019-14283)

It was discovered that the floppy driver in the Linux kernel did not
properly validate ioctl() calls, leading to a division-by-zero. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2019-14284)

Tuba Yavuz discovered that a race condition existed in the DesignWare USB3
DRD Controller device driver in the Linux kernel. A physically proximate
attacker could use this to cause a denial of service. (CVE-2019-14763)

It was discovered that an out-of-bounds read existed in the QLogic QEDI
iSCSI Initiator Driver in the Linux kernel. A local attacker could possibly
use this to expose sensitive information (kernel memory). (CVE-2019-15090)

It was discovered that the Raremono AM/FM/SW radio device driver in the
Linux kernel did not properly allocate memory, leading to a use-after-free.
A physically proximate attacker could use this to cause a denial of service
or possibly execute arbitrary code. (CVE-2019-15211)

It was discovered at a double-free error existed in the USB Rio 500 device
driver for the Linux kernel. A physically proximate attacker could use this
to cause a denial of service. (CVE-2019-15212)

It was discovered that a race condition existed in the Advanced Linux Sound
Architecture (ALSA) subsystem of the Linux kernel, leading to a potential
use-after-free. A physically proximate attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2019-15214)

It was discovered that a race condition existed in the CPiA2 video4linux
device driver for the Linux kernel, leading to a use-after-free. A
physically proximate attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2019-15215)

It was discovered that a race condition existed in the Softmac USB Prism54
device driver in the Linux kernel. A physically proximate attacker could
use this to cause a denial of service (system crash). (CVE-2019-15220)

It was discovered that a use-after-free vulnerability existed in the
AppleTalk implementation in the Linux kernel if an error occurs during
initialization. A local attacker could use this to cause a denial of
service (system crash). (CVE-2019-15292)

Jason Wang discovered that an infinite loop vulnerability existed in the
virtio net driver in the Linux kernel. A local attacker in a guest VM could
possibly use this to cause a denial of service in the host system.
(CVE-2019-3900)

Daniele Antonioli, Nils Ole Tippenhauer, and Kasper B. Rasmussen discovered
that the Bluetooth protocol BR/EDR specification did not properly require
sufficiently strong encryption key lengths. A physically proximate attacker
could use this to expose sensitive information. (CVE-2019-9506)

It was discovered that a race condition existed in the USB YUREX device
driver in the Linux kernel. A physically proximate attacker could use this
to cause a denial of service (system crash). (CVE-2019-15216)

It was discovered that the Siano USB MDTV receiver device driver in the
Linux kernel made improper assumptions about the device characteristics. A
physically proximate attacker could use this cause a denial of service
(system crash). (CVE-2019-15218)

It was discovered that the Line 6 POD USB device driver in the Linux kernel
did not properly validate data size information from the device. A
physically proximate attacker could use this to cause a denial of service
(system crash). (CVE-2019-15221)

Muyu Yu discovered that the CAN implementation in the Linux kernel in some
situations did not properly restrict the field size when processing
outgoing frames. A local attacker with CAP_NET_ADMIN privileges could use
this to execute arbitrary code. (CVE-2019-3701)

Vladis Dronov discovered that the debug interface for the Linux kernel's
HID subsystem did not properly validate passed parameters in some
situations. A local privileged attacker could use this to cause a denial of
service (infinite loop). (CVE-2019-3819)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 18.04
Ubuntu 16.04

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
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.
