Ubuntu Security Notice USN-6704-4
March 28, 2024
linux-intel-iotg, linux-intel-iotg-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-intel-iotg: Linux kernel for Intel IoT platforms
- linux-intel-iotg-5.15: Linux kernel for Intel IoT platforms
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)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 22.04 LTS:
linux-image-5.15.0-1051-intel-iotg 5.15.0-1051.57
linux-image-intel-iotg 5.15.0.1051.51
Ubuntu 20.04 LTS:
linux-image-5.15.0-1051-intel-iotg 5.15.0-1051.57~20.04.1
linux-image-intel 5.15.0.1051.57~20.04.41
linux-image-intel-iotg 5.15.0.1051.57~20.04.41
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-6707-4] Linux kernel (Azure) vulnerabilities
==========================================================================
Ubuntu Security Notice USN-6707-4
March 28, 2024
linux-azure-6.5 vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-azure-6.5: Linux kernel for Microsoft Azure cloud systems
Details:
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.

of service (system crash) or possibly execute arbitrary code.
(CVE-2024-1086)
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:
- Network drivers;
- PWM drivers;
(CVE-2024-26597, CVE-2024-26599)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 22.04 LTS:
linux-image-6.5.0-1017-azure 6.5.0-1017.17~22.04.1
linux-image-6.5.0-1017-azure-fde 6.5.0-1017.17~22.04.1
