Ubuntu Security Notice USN-6707-1
March 20, 2024
linux, linux-azure, linux-gcp, linux-gcp-6.5, linux-hwe-6.5,
linux-lowlatency, linux-lowlatency-hwe-6.5, linux-oem-6.5, linux-oracle,
linux-oracle-6.5, linux-raspi, linux-starfive, linux-starfive-6.5
vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 23.10
- Ubuntu 22.04 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-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-lowlatency: Linux low latency kernel
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-raspi: Linux kernel for Raspberry Pi systems
- linux-starfive: Linux kernel for StarFive processors
- linux-gcp-6.5: Linux kernel for Google Cloud Platform (GCP) systems
- linux-hwe-6.5: Linux hardware enablement (HWE) kernel
- linux-lowlatency-hwe-6.5: Linux low latency kernel
- linux-oem-6.5: Linux kernel for OEM systems
- linux-oracle-6.5: Linux kernel for Oracle Cloud systems
- linux-starfive-6.5: Linux kernel for StarFive processors
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.
(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)
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:

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.
