Linux Kernel, Tornado, Slurm, and more updates for Ubuntu

Ubuntu 7065 Published by

Ubuntu released a series of security notices that patch numerous vulnerabilities across the Linux kernel and several other widely used packages. The kernel updates target specialized builds for cloud platforms like Azure, Oracle, AWS, and IBM, as well as Raspberry Pi systems, addressing flaws in networking protocols, file systems, drivers, and memory management. Beyond the core operating system, developers also fixed critical issues in tools such as jq, Tornado, Slurm, OpenMPT, Rack::Session, and league/commonmark that could otherwise lead to remote code execution, denial of service attacks, or unauthorized data access.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 22.04 LTS
linux-image-5.15.0-1110-azure-fips 5.15.0-1110.119+fips1
Available with Ubuntu Pro
linux-image-azure-fips 5.15.0.1110.95
Available with Ubuntu Pro
linux-image-azure-fips-5.15 5.15.0.1110.95
Available with Ubuntu Pro

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.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 24.04 LTS
linux-image-6.8.0-2042-raspi-realtime 6.8.0-2042.43
Available with Ubuntu Pro
linux-image-raspi-realtime 6.8.0-2042.43
Available with Ubuntu Pro
linux-image-raspi-realtime-6.8 6.8.0-2042.43
Available with Ubuntu Pro

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.

linux-image-oracle-64k-6.8 6.8.0-1049.50~22.04.1

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.

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.

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

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

- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-raspi: Linux kernel for Raspberry Pi systems
- linux-raspi-5.4: Linux kernel for Raspberry Pi systems

Details:

Qualys discovered that several vulnerabilities existed in the AppArmor
Linux kernel Security Module (LSM). An unprivileged local attacker could
use these issues to load, replace, and remove arbitrary AppArmor profiles
causing denial of service, exposure of sensitive information (kernel
memory), local privilege escalation, or possibly escape a container.
(LP: #2143853)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
- x86 architecture;
- GPIO subsystem;
- GPU drivers;
- BTRFS file system;
- XFRM subsystem;
- IPv4 networking;
- IPv6 networking;
- MAC80211 subsystem;
- SMC sockets;
(CVE-2021-47599, CVE-2022-48875, CVE-2022-49072, CVE-2024-49927,
CVE-2024-56640, CVE-2025-21780, CVE-2025-40215)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 20.04 LTS
linux-image-5.4.0-1139-raspi 5.4.0-1139.152
Available with Ubuntu Pro
linux-image-raspi 5.4.0.1139.170
Available with Ubuntu Pro
linux-image-raspi-5.4 5.4.0.1139.170
Available with Ubuntu Pro
linux-image-raspi2 5.4.0.1139.170
Available with Ubuntu Pro

Ubuntu 18.04 LTS
linux-image-5.4.0-1139-raspi 5.4.0-1139.152~18.04.1
Available with Ubuntu Pro
linux-image-raspi-5.4 5.4.0.1139.152~18.04.1
Available with Ubuntu Pro
linux-image-raspi-hwe-18.04 5.4.0.1139.152~18.04.1
Available with Ubuntu Pro

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.
