ubuntu
Calendar Grey August 13, 2024
Dist Ubuntu Esm H88
A range of vulnerabilities addressed in Linux kernel tailored for Ubuntu's real-time and Raspberry Pi editions. Immediate action needed.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-lowlatency: Linux low latency kernel

- linux-raspi: Linux kernel for Raspberry Pi systems

Details:

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:

- ARM32 architecture;

- ARM64 architecture;

- M68K architecture;

- OpenRISC architecture;

- PowerPC architecture;

- RISC-V architecture;

- x86 architecture;

- Block layer subsystem;

- Accessibility subsystem;

- Bluetooth drivers;

- Clock framework and drivers;

- CPU frequency scaling framework;

- Hardware crypto device drivers;

- DMA engine subsystem;

- DPLL subsystem;

- FireWire subsystem;

- EFI core;

- Qualcomm firmware drivers;

- GPIO subsystem;

- GPU drivers;

- Microsoft Hyper-V drivers;

- InfiniBand drivers;

- IOMMU subsystem;

- IRQ chip drivers;

Update Instructions

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 24.04 LTS
   linux-image-6.8.0-1009-raspi    6.8.0-1009.10
   linux-image-6.8.0-40-lowlatency  6.8.0-40.40.1
   linux-image-6.8.0-40-lowlatency-64k  6.8.0-40.40.1
   linux-image-lowlatency          6.8.0-40.40.1
   linux-image-lowlatency-64k      6.8.0-40.40.1
   linux-image-raspi               6.8.0-1009.10

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.
