ubuntu

June 24, 2025

Several security issues were fixed in the Linux kernel.

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-gke: Linux kernel for Google Container Engine (GKE) systems

- linux-gkeop: Linux kernel for Google Container Engine (GKE) systems

- linux-ibm: Linux kernel for IBM cloud systems

- linux-kvm: Linux kernel for cloud environments

- linux-lowlatency: Linux low latency kernel

- linux-nvidia: Linux kernel for NVIDIA systems

- linux-nvidia-tegra: Linux kernel for NVIDIA Tegra systems

- linux-nvidia-tegra-igx: Linux kernel for NVIDIA Tegra IGX systems

- linux-oracle: Linux kernel for Oracle Cloud systems

Details:

Michael Randrianantenaina discovered that the Bluetooth driver in the Linux

Kernel contained an improper access control vulnerability. A nearby

attacker could use this to connect a rougue device and possibly execute

arbitrary code. (CVE-2024-8805)

It was discovered that the CIFS netw...

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.
