Ubuntu Security Notice USN-5265-1
February 03, 2022

linux, linux-aws, linux-aws-5.11, linux-aws-5.13, linux-gcp,
linux-gcp-5.11, linux-hwe-5.13, linux-kvm, linux-oem-5.13, linux-oracle,
linux-oracle-5.11, linux-raspi vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 21.10
- Ubuntu 20.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux: Linux kernel
- linux-aws: Linux kernel for Amazon Web Services (AWS) systems
- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-kvm: Linux kernel for cloud environments
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-raspi: Linux kernel for Raspberry Pi systems
- linux-aws-5.11: Linux kernel for Amazon Web Services (AWS) systems
- linux-aws-5.13: Linux kernel for Amazon Web Services (AWS) systems
- linux-gcp-5.11: Linux kernel for Google Cloud Platform (GCP) systems
- linux-hwe-5.13: Linux hardware enablement (HWE) kernel
- linux-oem-5.13: Linux kernel for OEM systems
- linux-oracle-5.11: Linux kernel for Oracle Cloud systems

Details:

Jeremy Cline discovered a use-after-free in the nouveau graphics driver of
the Linux kernel during device removal. A privileged or physically
proximate attacker could use this to cause a denial of service (system
crash). (CVE-2020-27820)

It was discovered that the Bluetooth subsystem 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-2021-3640)

Likang Luo discovered that a race condition existed in the Bluetooth
subsystem of the Linux kernel, leading to 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-2021-3752)

It was discovered that the SCTP protocol implementation in the Linux kernel
did not properly verify VTAGs in some situations. A remote attacker could
possibly use this to cause a denial of service (connection disassociation).
(CVE-2021-3772)

It was discovered that the eBPF implementation in the Linux kernel
contained a race condition around read-only maps. A privileged attacker
could use this to modify read-only maps. (CVE-2021-4001)

It was discovered that the NFS server implementation in the Linux kernel
contained an out-of-bounds write vulnerability. A local attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2021-4090)

Felix Wilhelm discovered that the KVM implementation in the Linux kernel
did not properly handle exit events from AMD Secure Encrypted
Virtualization-Encrypted State (SEV-ES) guest VMs. An attacker in a guest
VM could use this to cause a denial of service (host kernel crash) or
possibly execute arbitrary code in the host kernel. (CVE-2021-4093)

Lin Ma discovered that the NFC Controller Interface (NCI) implementation in
the Linux kernel contained a race condition, leading to 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-2021-4202)

It was discovered that the AMD Radeon GPU driver in the Linux kernel did
not properly validate writes in the debugfs file system. A privileged
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2021-42327)

Luo Likang discovered that the FireDTV Firewire driver in the Linux kernel
did not properly perform bounds checking in some situations. A local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2021-42739)

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.

Ubuntu Security Notice USN-5268-1
February 03, 2022

linux, linux-aws, linux-aws-hwe, linux-azure, linux-dell300x,
linux-gcp-4.15, linux-hwe, linux-kvm, linux-oracle, linux-raspi2,
linux-snapdragon vulnerabilities

==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.04 LTS
- Ubuntu 16.04 ESM
- Ubuntu 14.04 ESM

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux: Linux kernel
- linux-aws: Linux kernel for Amazon Web Services (AWS) systems

- linux-dell300x: Linux kernel for Dell 300x platforms
- linux-gcp-4.15: Linux kernel for Google Cloud Platform (GCP) systems

- linux-kvm: Linux kernel for cloud environments
- linux-oracle: Linux kernel for Oracle Cloud systems

- linux-aws-hwe: Linux kernel for Amazon Web Services (AWS-HWE) systems
- linux-azure: Linux kernel for Microsoft Azure Cloud systems
- linux-hwe: Linux hardware enablement (HWE) kernel

Details:

Keyu Man discovered that the ICMP implementation in the Linux kernel did
not properly handle received ICMP error packets. A remote attacker could
use this to facilitate attacks on UDP based services that depend on source
port randomization. (CVE-2021-20322)

It was discovered that the Bluetooth subsystem 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-2021-3640)

Likang Luo discovered that a race condition existed in the Bluetooth
subsystem of the Linux kernel, leading to a use-after-free vulnerability. A
