Ubuntu Security Notice USN-8098-2
March 17, 2026
linux-gcp vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-gcp: Linux kernel for Google Cloud Platform (GCP) 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;
- MMC subsystem;
- BTRFS file system;
- XFRM subsystem;
- IPv4 networking;
- IPv6 networking;
- MAC80211 subsystem;
- SMC sockets;
(CVE-2021-47599, CVE-2022-48875, CVE-2022-49072, CVE-2022-49267,
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-5.4.0-1159-gcp 5.4.0-1159.168
Available with Ubuntu Pro
linux-image-gcp-5.4 5.4.0.1159.161
Available with Ubuntu Pro
linux-image-gcp-lts-20.04 5.4.0.1159.161
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.

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.

[USN-8094-2] Linux kernel vulnerabilities
==========================================================================
Ubuntu Security Notice USN-8094-2
March 17, 2026
linux-gcp-6.17, linux-realtime vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 25.10
- Ubuntu 24.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-realtime: Linux kernel for Real-time systems
- linux-gcp-6.17: Linux kernel for Google Cloud Platform (GCP) 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)
It was discovered that some AMD Zen 5 processors supporting RDSEED
instruction did not properly handle entropy, potentially resulting in the
consumption of insufficiently random values. A local attacker could
possibly use this issue to influence the values returned by the RDSEED
instruction causing loss of confidentiality and integrity. (CVE-2025-62626)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 25.10
linux-image-6.17.0-1008-realtime 6.17.0-1008.9
linux-image-realtime 6.17.0-1008.9
linux-image-realtime-6.17 6.17.0-1008.9
linux-image-realtime-hwe-24.04 6.17.0-1008.9
Ubuntu 24.04 LTS
linux-image-6.17.0-1009-gcp 6.17.0-1009.9~24.04.3
linux-image-6.17.0-1009-gcp-64k 6.17.0-1009.9~24.04.3
linux-image-gcp 6.17.0-1009.9~24.04.3
linux-image-gcp-6.17 6.17.0-1009.9~24.04.3
linux-image-gcp-64k 6.17.0-1009.9~24.04.3
linux-image-gcp-64k-6.17 6.17.0-1009.9~24.04.3
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 22.04 LTS
linux-image-5.15.0-1102-realtime 5.15.0-1102.111
Available with Ubuntu Pro
linux-image-realtime 5.15.0.1102.106
Available with Ubuntu Pro
linux-image-realtime-5.15 5.15.0.1102.106
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.

[USN-8096-3] Linux kernel vulnerabilities
==========================================================================
Ubuntu Security Notice USN-8096-3
March 17, 2026
linux-aws-5.15, linux-gcp-5.15, linux-gke, linux-hwe-5.15,
linux-intel-iotg-5.15, linux-lowlatency-hwe-5.15, linux-oracle-5.15
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-gke: Linux kernel for Google Container Engine (GKE) systems
- linux-aws-5.15: Linux kernel for Amazon Web Services (AWS) systems
- linux-gcp-5.15: Linux kernel for Google Cloud Platform (GCP) systems
- linux-hwe-5.15: Linux hardware enablement (HWE) kernel
- linux-intel-iotg-5.15: Linux kernel for Intel IoT platforms
- linux-lowlatency-hwe-5.15: Linux low latency kernel
- linux-oracle-5.15: Linux kernel for Oracle Cloud 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.

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.

[USN-8102-1] snapd vulnerability
==========================================================================
Ubuntu Security Notice USN-8102-1
March 17, 2026
snapd vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 25.10
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
Summary:
snapd could be used to escalate privilege
Software Description:
- snapd: Daemon and tooling that enable snap packages
Details:
Qualys discovered that snapd incorrectly handled certain operations in the
snap's private /tmp directory. If systemd-tmpfiles is enabled to automatically
clean up this directory, a local attacker could possibly use this issue to
re-create the deleted directory, resulting in privilege escalation.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 25.10
snapd 2.73+ubuntu25.10.1
Ubuntu 24.04 LTS
snapd 2.73+ubuntu24.04.1
