Details

It was discovered that the alarmtimer implementation in the Linux kernel
contained an integer overflow vulnerability. A local attacker could use
this to cause a denial of service. (CVE-2018-13053)

Wen Xu discovered that the XFS filesystem implementation in the Linux
kernel did not properly track inode validations. An attacker could use this
to construct a malicious XFS image that, when mounted, could cause a denial
of service (system crash). (CVE-2018-13093)

Wen Xu discovered that the f2fs file system implementation in the
Linux kernel did not properly validate metadata. An attacker could
use this to construct a malicious f2fs image that, when mounted,
could cause a denial of service (system crash). (CVE-2018-13097,
CVE-2018-13099, CVE-2018-13100, CVE-2018-14614, CVE-2018-14616,
CVE-2018-13096, CVE-2018-13098, CVE-2018-14615)

Wen Xu and Po-Ning Tseng discovered that btrfs file system
implementation in the Linux kernel did not properly validate
metadata. An attacker could use this to construct a malicious
btrfs image that, when mounted, could cause a denial of service
(system crash). (CVE-2018-14610, CVE-2018-14611, CVE-2018-14612,
CVE-2018-14613, CVE-2018-14609)

Wen Xu discovered that the HFS+ filesystem implementation in the Linux
kernel did not properly handle malformed catalog data in some situations.
An attacker could use this to construct a malicious HFS+ image that, when
mounted, could cause a denial of service (system crash). (CVE-2018-14617)

Vasily Averin and Pavel Tikhomirov discovered that the cleancache subsystem
of the Linux kernel did not properly initialize new files in some
situations. A local attacker could use this to expose sensitive
information. (CVE-2018-16862)

Hui Peng and Mathias Payer discovered that the USB subsystem in the Linux
kernel did not properly handle size checks when handling an extra USB
descriptor. A physically proximate attacker could use this to cause a
denial of service (system crash). (CVE-2018-20169)

It was discovered that a use-after-free error existed in the block layer
subsystem of the Linux kernel when certain failure conditions occurred. A
local attacker could possibly use this to cause a denial of service (system
crash) or possibly execute arbitrary code. (CVE-2018-20856)

Eli Biham and Lior Neumann discovered that the Bluetooth implementation in
the Linux kernel did not properly validate elliptic curve parameters during
Diffie-Hellman key exchange in some situations. An attacker could use this
to expose sensitive information. (CVE-2018-5383)

It was discovered that a heap buffer overflow existed in the Marvell
Wireless LAN device driver for the Linux kernel. An attacker could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2019-10126)

Andrei Vlad Lutas and Dan Lutas discovered that some x86 processors
incorrectly handle SWAPGS instructions during speculative execution. A
local attacker could use this to expose sensitive information (kernel
memory). (CVE-2019-1125)

It was discovered that the PowerPC dlpar implementation in the Linux kernel
did not properly check for allocation errors in some situations. A local
attacker could possibly use this to cause a denial of service (system
crash). (CVE-2019-12614)

It was discovered that a NULL pointer dereference vulnerabilty existed in
the Near-field communication (NFC) implementation in the Linux kernel. An
attacker could use this to cause a denial of service (system crash).
(CVE-2019-12818)

It was discovered that the MDIO bus devices subsystem in the Linux kernel
improperly dropped a device reference in an error condition, leading to a
use-after-free. An attacker could use this to cause a denial of service
(system crash). (CVE-2019-12819)

It was discovered that a NULL pointer dereference vulnerability existed in
the Near-field communication (NFC) implementation in the Linux kernel. A
local attacker could use this to cause a denial of service (system crash).
(CVE-2019-12984)

Jann Horn discovered a use-after-free vulnerability in the Linux kernel
when accessing LDT entries in some situations. A local attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2019-13233)

Jann Horn discovered that the ptrace implementation in the Linux kernel did
not properly record credentials in some situations. A local attacker could
use this to cause a denial of service (system crash) or possibly gain
administrative privileges. (CVE-2019-13272)

It was discovered that the Empia EM28xx DVB USB device driver
implementation in the Linux kernel contained a use-after-free vulnerability
when disconnecting the device. An attacker could use this to cause a denial
of service (system crash). (CVE-2019-2024)

It was discovered that the USB video device class implementation in the
Linux kernel did not properly validate control bits, resulting in an out of
bounds buffer read. A local attacker could use this to possibly expose
sensitive information (kernel memory). (CVE-2019-2101)

It was discovered that the Marvell Wireless LAN device driver in the Linux
kernel did not properly validate the BSS descriptor. A local attacker could
possibly use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2019-3846)

It was discovered that the Appletalk IP encapsulation driver in the Linux
kernel did not properly prevent kernel addresses from being copied to user
space. A local attacker with the CAP_NET_ADMIN capability could use this to
expose sensitive information. (CVE-2018-20511)

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.
