4 October 2019
linux, linux-aws, linux-azure, linux-gcp, linux-gke-5.0, linux-hwe, linux-kvm, linux-raspi2, linux-snapdragon vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
o Ubuntu 19.04
o Ubuntu 18.04 LTS
Summary
Several security issues were fixed in the Linux kernel.
Software Description
o linux - Linux kernel
o linux-aws - Linux kernel for Amazon Web Services (AWS) systems
o linux-azure - Linux kernel for Microsoft Azure Cloud systems
o linux-gcp - Linux kernel for Google Cloud Platform (GCP) systems
o linux-kvm - Linux kernel for cloud environments
o linux-raspi2 - Linux kernel for Raspberry Pi 2
o linux-snapdragon - Linux kernel for Snapdragon processors
o linux-gke-5.0 - Linux kernel for Google Container Engine (GKE) systems
o linux-hwe - Linux hardware enablement (HWE) kernel
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)

To update your system, please follow these instructions: https://
wiki.ubuntu.com/Security/Upgrades .
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.
