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

- Ubuntu 22.04 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-ibm: Linux kernel for IBM cloud systems
- linux-intel-iotg: Linux kernel for Intel IoT platforms
- linux-kvm: Linux kernel for cloud environments
- linux-lowlatency: Linux low latency kernel
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-raspi: Linux kernel for Raspberry Pi systems

Details:

It was discovered that the Linux kernel did not properly restrict access to
the kernel debugger when booted in secure boot environments. A privileged
attacker could use this to bypass UEFI Secure Boot restrictions.
(CVE-2022-21499)

Aaron Adams discovered that the netfilter subsystem in the Linux kernel did
not properly handle the removal of stateful expressions in some situations,
leading to a use-after-free vulnerability. A local attacker could use this
to cause a denial of service (system crash) or execute arbitrary code.
(CVE-2022-1966)

Billy Jheng Bing Jhong discovered that the CIFS network file system
implementation in the Linux kernel did not properly validate arguments to
ioctl() in some situations. A local attacker could possibly use this to
cause a denial of service (system crash). (CVE-2022-0168)

Hu Jiahui discovered that multiple race conditions existed in the Advanced
Linux Sound Architecture (ALSA) framework, leading to use-after-free
vulnerabilities. A local attacker could use these to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2022-1048)

Qiuhao Li, Gaoning Pan and Yongkang Jia discovered that the KVM
implementation in the Linux kernel did not properly perform guest page
table updates in some situations. An attacker in a guest vm could possibly
use this to crash the host OS. (CVE-2022-1158)

It was discovered that the implementation of the 6pack and mkiss protocols
in the Linux kernel did not handle detach events properly in some
situations, leading to a use-after-free vulnerability. A local attacker
could possibly use this to cause a denial of service (system crash).
(CVE-2022-1195)

Duoming Zhou discovered that the 6pack protocol implementation in the Linux
kernel did not handle detach events properly in some situations, leading to
a use-after-free vulnerability. A local attacker could use this to cause a
denial of service (system crash). (CVE-2022-1198)

Duoming Zhou discovered that the AX.25 amateur radio protocol
implementation in the Linux kernel did not handle detach events properly in
some situations. A local attacker could possibly use this to cause a denial
of service (system crash) or execute arbitrary code. (CVE-2022-1199)

Duoming Zhou discovered race conditions in the AX.25 amateur radio protocol
implementation in the Linux kernel during device detach operations. A local
attacker could possibly use this to cause a denial of service (system
crash). (CVE-2022-1204)

Duoming Zhou discovered race conditions in the AX.25 amateur radio protocol
implementation in the Linux kernel, leading to use-after-free
vulnerabilities. A local attacker could possibly use this to cause a denial
of service (system crash). (CVE-2022-1205)

Qiuhao Li, Gaoning Pan, and Yongkang Jia discovered that the kvm
implementation in the Linux kernel did not handle releasing a virtual cpu
properly. A local attacker in a guest VM coud possibly use this to cause a
denial of service (host system crash). (CVE-2022-1263)

It was discovered that the PF_KEYv2 implementation in the Linux kernel did
not properly initialize kernel memory in some situations. A local attacker
could use this to expose sensitive information (kernel memory).
(CVE-2022-1353)

It was discovered that the implementation of X.25 network protocols in the
Linux kernel did not terminate link layer sessions properly. A local
attacker could possibly use this to cause a denial of service (system
crash). (CVE-2022-1516)

It was discovered that the ACRN Hypervisor Service Module implementation in
the Linux kernel did not properly deallocate memory in some situations. A
local privileged attacker could possibly use this to cause a denial of
service (memory exhaustion). (CVE-2022-1651)

It was discovered that the RxRPC session socket implementation in the Linux
kernel did not properly handle ioctls called when no security protocol is
given. A local attacker could use this to cause a denial of service (system
crash) or possibly expose sensitive information (kernel memory).
(CVE-2022-1671)

Ziming Zhang discovered that the netfilter subsystem in the Linux kernel
did not properly validate sets with multiple ranged fields. A local
attacker could use this to cause a denial of service or execute arbitrary
code. (CVE-2022-1972)

赵子轩 discovered that the 802.2 LLC type 2 driver in the Linux kernel did not
properly perform reference counting in some error conditions. A local
attacker could use this to cause a denial of service. (CVE-2022-28356)

It was discovered that the 8 Devices USB2CAN interface implementation in
the Linux kernel did not properly handle certain error conditions, leading
to a double-free. A local attacker could possibly use this to cause a
denial of service (system crash). (CVE-2022-28388)

It was discovered that the Microchip CAN BUS Analyzer interface
implementation in the Linux kernel did not properly handle certain error
conditions, leading to a double-free. A local attacker could possibly use
this to cause a denial of service (system crash). (CVE-2022-28389)

It was discovered that the EMS CAN/USB interface implementation in the
Linux kernel contained a double-free vulnerability when handling certain
error conditions. A local attacker could use this to cause a denial of
service (memory exhaustion). (CVE-2022-28390)

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.
