Details

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)

It was discovered that the Bluetooth UART implementation in the Linux
kernel did not properly check for missing tty operations. A local attacker
could use this to cause a denial of service. (CVE-2019-10207)

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)

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)

Hui Peng and Mathias Payer discovered that the USB audio driver for the
Linux kernel did not properly validate device meta data. A physically
proximate attacker could use this to cause a denial of service (system
crash). (CVE-2019-15117)

Hui Peng and Mathias Payer discovered that the USB audio driver for the
Linux kernel improperly performed recursion while handling device meta
data. A physically proximate attacker could use this to cause a denial of
service (system crash). (CVE-2019-15118)

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 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)

Benjamin Moody discovered that the XFS file system in the Linux kernel did
not properly handle an error condition when out of disk quota. A local
attacker could possibly use this to cause a denial of service.
(CVE-2019-15538)

It was discovered that the Hisilicon HNS3 ethernet device driver in the
Linux kernel contained an out of bounds access vulnerability. A local
attacker could use this to possibly cause a denial of service (system
crash). (CVE-2019-15925)

It was discovered that the Atheros mobile chipset driver in the Linux
kernel did not properly validate data in some situations. An attacker could
use this to cause a denial of service (system crash). (CVE-2019-15926)

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 ZR364XX Camera USB device driver for the Linux
kernel did not properly initialize memory. A physically proximate attacker
could use this to cause a denial of service (system crash).
(CVE-2019-15217)

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)

It was discovered that the Line 6 USB driver for the Linux kernel contained
a race condition when the device was disconnected. A physically proximate
attacker could use this to cause a denial of service (system crash).
(CVE-2019-15223)

Update instructions

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

Ubuntu 19.04
Ubuntu 18.04

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.
