Details

It was discovered that a heap-based buffer overflow existed in the Marvell
WiFi-Ex Driver for the Linux kernel. A physically proximate attacker could
use this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2019-14895, CVE-2019-14901)

It was discovered that a heap-based buffer overflow existed in the Marvell
Libertas WLAN Driver for the Linux kernel. A physically proximate attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2019-14896, CVE-2019-14897)

It was discovered that the Fujitsu ES network device driver for the Linux
kernel did not properly check for errors in some situations, leading to a
NULL pointer dereference. A local attacker could use this to cause a denial
of service. (CVE-2019-16231)

Anthony Steinhauser discovered that the Linux kernel did not properly
perform Spectre_RSB mitigations to all processors for PowerPC architecture
systems in some situations. A local attacker could use this to expose
sensitive information. (CVE-2019-18660)

It was discovered that the Broadcom V3D DRI driver in the Linux kernel did
not properly deallocate memory in certain error conditions. A local
attacker could possibly use this to cause a denial of service (kernel
memory exhaustion). (CVE-2019-19044)

It was discovered that the Mellanox Technologies Innova driver in the Linux
kernel did not properly deallocate memory in certain failure conditions. A
local attacker could use this to cause a denial of service (kernel memory
exhaustion). (CVE-2019-19045)

It was discovered that the Mellanox Technologies ConnectX driver in the
Linux kernel did not properly deallocate memory in certain failure
conditions. A local attacker could use this to cause a denial of service
(kernel memory exhaustion). (CVE-2019-19047)

It was discovered that the Intel WiMAX 2400 driver in the Linux kernel did
not properly deallocate memory in certain situations. A local attacker
could use this to cause a denial of service (kernel memory exhaustion).
(CVE-2019-19051)

It was discovered that Geschwister Schneider USB CAN interface driver in
the Linux kernel did not properly deallocate memory in certain failure
conditions. A physically proximate attacker could use this to cause a
denial of service (kernel memory exhaustion). (CVE-2019-19052)

It was discovered that the netlink-based 802.11 configuration interface in
the Linux kernel did not deallocate memory in certain error conditions. A
local attacker could possibly use this to cause a denial of service (kernel
memory exhaustion). (CVE-2019-19055)

It was discovered that the event tracing subsystem of the Linux kernel did
not properly deallocate memory in certain error conditions. A local
attacker could use this to cause a denial of service (kernel memory
exhaustion). (CVE-2019-19072)

It was discovered that the driver for memoryless force-feedback input
devices in the Linux kernel contained a use-after-free vulnerability. A
physically proximate attacker could possibly use this to cause a denial of
service (system crash) or execute arbitrary code. (CVE-2019-19524)

It was discovered that the Microchip CAN BUS Analyzer driver in the Linux
kernel contained a use-after-free vulnerability on device disconnect. A
physically proximate attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2019-19529)

It was discovered that the PEAK-System Technik USB driver in the Linux
kernel did not properly sanitize memory before sending it to the device. A
physically proximate attacker could use this to expose sensitive
information (kernel memory). (CVE-2019-19534)

Tristan Madani discovered that the ALSA timer implementation in the Linux
kernel contained a use-after-free vulnerability. A local attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2019-19807)

It was discovered that the DesignWare USB3 controller driver in the Linux
kernel did not properly deallocate memory in some error conditions. A local
attacker could possibly use this to cause a denial of service (memory
exhaustion). (CVE-2019-18813)

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.
