Ubuntu Security Notice USN-7173-1
December 17, 2024
linux, linux-gcp, linux-gcp-5.4, linux-hwe-5.4, linux-kvm, linux-raspi
vulnerabilities
==========================================================================
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: Linux kernel
- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-kvm: Linux kernel for cloud environments
- linux-raspi: Linux kernel for Raspberry Pi systems
- linux-gcp-5.4: Linux kernel for Google Cloud Platform (GCP) systems
- linux-hwe-5.4: Linux hardware enablement (HWE) kernel
Details:
Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not
properly handle certain error conditions, leading to a NULL pointer
dereference. A local attacker could possibly trigger this vulnerability to
cause a denial of service. (CVE-2022-38096)

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.
