o Ubuntu 16.04 ESM
o Ubuntu 14.04 ESM
Packages
o linux - Linux kernel
o linux-aws - Linux kernel for Amazon Web Services (AWS) systems
o linux-aws-hwe - Linux kernel for Amazon Web Services (AWS-HWE) systems
o linux-azure - Linux kernel for Microsoft Azure Cloud systems
o linux-azure-4.15 - Linux kernel for Microsoft Azure Cloud systems
o linux-gcp - Linux kernel for Google Cloud Platform (GCP) systems

Details
It was discovered that the bluetooth subsystem in the Linux kernel did not
properly handle HCI device initialization failure, leading to a double-free
vulnerability. An attacker could use this to cause a denial of service or
possibly execute arbitrary code. ( CVE-2021-3564 )
It was discovered that the bluetooth subsystem in the Linux kernel did not
properly handle HCI device detach events, leading to a use-after-free
vulnerability. An attacker could use this to cause a denial of service or
possibly execute arbitrary code. ( CVE-2021-3573 )
It was discovered that the NFC implementation in the Linux kernel did not
properly handle failed connect events leading to a NULL pointer
dereference. A local attacker could use this to cause a denial of service.
( CVE-2021-3587 )

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.

Details
Norbert Slusarek discovered that the CAN broadcast manger (bcm) protocol
implementation in the Linux kernel did not properly initialize memory in
some situations. A local attacker could use this to expose sensitive
information (kernel memory). ( CVE-2021-34693 )
It was discovered that the bluetooth subsystem in the Linux kernel did not
properly handle HCI device initialization failure, leading to a double-free
vulnerability. An attacker could use this to cause a denial of service or
possibly execute arbitrary code. ( CVE-2021-3564 )
It was discovered that the bluetooth subsystem in the Linux kernel did not
properly handle HCI device detach events, leading to a use-after-free
vulnerability. An attacker could use this to cause a denial of service or
possibly execute arbitrary code. ( CVE-2021-3573 )
It was discovered that the NFC implementation in the Linux kernel did not
properly handle failed connect events leading to a NULL pointer
dereference. A local attacker could use this to cause a denial of service.
( CVE-2021-3587 )

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.

USN-5046-1: Linux kernel vulnerabilities
18 August 2021
Several security issues were fixed in the Linux kernel.
Releases
o Ubuntu 21.04
o Ubuntu 20.04 LTS
Packages
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-hwe-5.11 - Linux hardware enablement (HWE) kernel
o linux-oracle - Linux kernel for Oracle Cloud systems
o linux-raspi - Linux kernel for Raspberry Pi (V8) systems
Details
It was discovered that the bluetooth subsystem in the Linux kernel did not
properly perform access control. An authenticated attacker could possibly
use this to expose sensitive information. ( CVE-2020-26558 , CVE-2021-0129 )
Michael Brown discovered that the Xen netback driver in the Linux kernel
did not properly handle malformed packets from a network PV frontend,
leading to a use-after-free vulnerability. An attacker in a guest VM could
use this to cause a denial of service or possibly execute arbitrary code.
( CVE-2021-28691 )
It was discovered that the bluetooth subsystem in the Linux kernel did not
properly handle HCI device initialization failure, leading to a double-free
vulnerability. An attacker could use this to cause a denial of service or
possibly execute arbitrary code. ( CVE-2021-3564 )
It was discovered that the bluetooth subsystem in the Linux kernel did not
properly handle HCI device detach events, leading to a use-after-free
vulnerability. An attacker could use this to cause a denial of service or
possibly execute arbitrary code. ( CVE-2021-3573 )
It was discovered that the NFC implementation in the Linux kernel did not
properly handle failed connect events leading to a NULL pointer
dereference. A local attacker could use this to cause a denial of service.
( CVE-2021-3587 )

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.
