A security issue affects these releases of Ubuntu and its derivatives:
=2D Ubuntu 24.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
=2D linux: Linux kernel
=2D linux-aws: Linux kernel for Amazon Web Services (AWS) systems
=2D linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
=2D linux-gke: Linux kernel for Google Container Engine (GKE) systems
=2D linux-ibm: Linux kernel for IBM cloud systems
=2D linux-nvidia: Linux kernel for NVIDIA systems
=2D linux-oem-6.8: Linux kernel for OEM systems
=2D linux-raspi: Linux kernel for Raspberry Pi systems
Details:
Benedict Schl=C3=BCter, Supraja Sridhara, Andrin Bertschi, and Shweta Shinde
discovered that an untrusted hypervisor could inject malicious #VC
interrupts and compromise the security guarantees of AMD SEV-SNP. This flaw
is known as WeSee. A local attacker in control of the hypervisor could use
this to expose sensitive information or possibly execute arbitrary code in
the trusted execution environment. (CVE-2024-25742)
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:
- DMA engine subsystem;
- HID subsystem;
- I2C subsystem;
- PHY drivers;
- TTY drivers;
- IPv4 networking;
(CVE-2024-35990, CVE-2024-35997, CVE-2024-35992, CVE-2024-35984,
CVE-2024-36008, CVE-2024-36016)

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.
