Ubuntu Security Notice USN-5594-1

Ubuntu Security Notice USN-5594-1
Posted Sep 2, 2022
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 5594-1 - Asaf Modelevsky discovered that the Intel 10GbE PCI Express Ethernet driver for the Linux kernel performed insufficient control flow management. A local attacker could possibly use this to cause a denial of service. 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.

=========================================================================
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.
