- Ubuntu 18.04 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-oracle: Linux kernel for Oracle Cloud systems
- linux-raspi: Linux kernel for Raspberry Pi systems
- linux-aws-5.4: Linux kernel for Amazon Web Services (AWS) systems
- linux-azure-5.4: Linux kernel for Microsoft Azure cloud systems
- linux-gcp-5.4: Linux kernel for Google Cloud Platform (GCP) systems
- linux-hwe-5.4: Linux hardware enablement (HWE) kernel
- linux-ibm-5.4: Linux kernel for IBM cloud systems
- linux-oracle-5.4: Linux kernel for Oracle Cloud systems
- linux-raspi-5.4: Linux kernel for Raspberry Pi systems

Details:

It was discovered that the Traffic-Control Index (TCINDEX) implementation
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-2023-1281)

Jiasheng Jiang discovered that the HSA Linux kernel driver for AMD Radeon
GPU devices did not properly validate memory allocation in certain
situations, leading to a null pointer dereference vulnerability. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2022-3108)

It was discovered that the infrared transceiver USB driver did not properly
handle USB control messages. A local attacker with physical access could
plug in a specially crafted USB device to cause a denial of service (memory
exhaustion). (CVE-2022-3903)

Haowei Yan discovered that a race condition existed in the Layer 2
Tunneling Protocol (L2TP) implementation in the Linux kernel. A local
attacker could possibly use this to cause a denial of service (system
crash). (CVE-2022-4129)

It was discovered that the Human Interface Device (HID) support driver in
the Linux kernel contained a type confusion vulnerability in some
situations. A local attacker could use this to cause a denial of service
(system crash). (CVE-2023-1073)

It was discovered that a memory leak existed in the SCTP protocol
implementation in the Linux kernel. A local attacker could use this to
cause a denial of service (memory exhaustion). (CVE-2023-1074)

Lianhui Tang discovered that the MPLS implementation in the Linux kernel
did not properly handle certain sysctl allocation failure conditions,
leading to a double-free vulnerability. An attacker could use this to cause
a denial of service or possibly execute arbitrary code. (CVE-2023-26545)

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.
