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

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

- Ubuntu 22.04 LTS
- 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-azure: Linux kernel for Microsoft Azure Cloud systems
- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-gke: Linux kernel for Google Container Engine (GKE) systems
- linux-gkeop: Linux kernel for Google Container Engine (GKE) systems
- linux-ibm: Linux kernel for IBM cloud systems
- linux-kvm: Linux kernel for cloud environments
- linux-lowlatency: Linux low latency kernel
- linux-aws-5.15: Linux kernel for Amazon Web Services (AWS) systems
- linux-azure-5.15: Linux kernel for Microsoft Azure cloud systems
- linux-gcp-5.15: Linux kernel for Google Cloud Platform (GCP) systems
- linux-gke-5.15: Linux kernel for Google Container Engine (GKE) systems

Details:

Asaf Modelevsky discovered that the Intel(R) 10GbE PCI Express (ixgbe)
Ethernet driver for the Linux kernel performed insufficient control flow
management. A local attacker could possibly use this to cause a denial of
service. (CVE-2021-33061)

It was discovered that the IP implementation in the Linux kernel did not
provide sufficient randomization when calculating port offsets. An attacker
could possibly use this to expose sensitive information. (CVE-2022-1012)

Norbert Slusarek discovered that a race condition existed in the perf
subsystem in the Linux kernel, resulting in a use-after-free vulnerability.
A privileged local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2022-1729)

Qiuhao Li, Gaoning Pan, and Yongkang Jia discovered that the KVM hypervisor
implementation in the Linux kernel did not properly handle an illegal
instruction in a guest, resulting in a null pointer dereference. An
attacker in a guest VM could use this to cause a denial of service (system
crash) in the host OS. (CVE-2022-1852)

It was discovered that the UDF file system 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-2022-1943)

Gerald Lee discovered that the NTFS file system implementation in the Linux
kernel did not properly handle certain error conditions, leading to a use-
after-free vulnerability. A local attacker could use this to cause a denial
of service (system crash) or possibly expose sensitive information.
(CVE-2022-1973)

It was discovered that the device-mapper verity (dm-verity) driver in the
Linux kernel did not properly verify targets being loaded into the device-
mapper table. A privileged attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2022-2503)

Zheyu Ma discovered that the Intel iSMT SMBus host controller driver 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).
(CVE-2022-2873)

Selim Enes Karaduman discovered that a race condition existed in the pipe
buffers implementation of the Linux kernel. A local attacker could use this
to cause a denial of service (system crash) or possibly escalate
privileges. (CVE-2022-2959)

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.
