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

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-azure: Linux kernel for Microsoft Azure Cloud systems
- linux-azure-fde: Linux kernel for Microsoft Azure CVM 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-nvidia: Linux kernel for NVIDIA systems
- linux-azure-5.15: Linux kernel for Microsoft Azure cloud systems
- linux-azure-fde-5.15: Linux kernel for Microsoft Azure CVM cloud systems
- linux-gcp-5.15: Linux kernel for Google Cloud Platform (GCP) systems
- linux-gkeop-5.15: Linux kernel for Google Container Engine (GKE) systems
- linux-hwe-5.15: Linux hardware enablement (HWE) kernel
- linux-ibm-5.15: Linux kernel for IBM cloud systems
- linux-lowlatency-hwe-5.15: Linux low latency kernel

Details:

It was discovered that the NVIDIA Tegra XUSB pad controller driver in the
Linux kernel did not properly handle return values in certain error
conditions. A local attacker could use this to cause a denial of service
(system crash). (CVE-2023-23000)

Quentin Minster discovered that the KSMBD implementation in the Linux
kernel did not properly handle session setup requests. A remote attacker
could possibly use this to cause a denial of service (memory exhaustion).
(CVE-2023-32247)

Lonial Con discovered that the netfilter subsystem in the Linux kernel did
not properly handle element deactivation in certain cases, 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-2024-1085)

Notselwyn discovered that the netfilter subsystem in the Linux kernel did
not properly handle verdict parameters in certain cases, 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-2024-1086)

It was discovered that a race condition existed in the SCSI Emulex
LightPulse Fibre Channel driver in the Linux kernel when unregistering FCF
and re-scanning an HBA FCF table, leading to a null pointer dereference
vulnerability. A local attacker could use this to cause a denial of service
(system crash). (CVE-2024-24855)

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.
