vulnerabilities
==========================================================================

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-oracle: Linux kernel for Oracle Cloud 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-ibm-5.15: Linux kernel for IBM cloud systems
- linux-lowlatency-hwe-5.15: Linux low latency kernel
- linux-oracle-5.15: Linux kernel for Oracle Cloud systems

Details:

It was discovered that the Open vSwitch implementation in the Linux kernel
could overflow its stack during recursive action operations under certain
conditions. A local attacker could use this to cause a denial of service
(system crash). (CVE-2024-1151)

Sander Wiebing, Alvise de Faveri Tron, Herbert Bos, and Cristiano Giuffrida
discovered that the Linux kernel mitigations for the initial Branch History
Injection vulnerability (CVE-2022-0001) were insufficient for Intel
processors. A local attacker could potentially use this to expose sensitive
information. (CVE-2024-2201)

Chenyuan Yang discovered that the RDS Protocol implementation in the Linux
kernel contained an out-of-bounds read vulnerability. An attacker could use
this to possibly cause a denial of service (system crash). (CVE-2024-23849)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

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.
