The latest update to the Ubuntu kernel addresses various vulnerabilities, enhancing protection against potential threats and boosting overall system reliability.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-oracle: Linux kernel for Oracle Cloud systems

Details:

It was discovered that a race condition existed in the Bluetooth subsystem

in the Linux kernel when modifying certain settings values through debugfs.

A privileged local attacker could use this to cause a denial of service.

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:

- ARM64 architecture;

- RISC-V architecture;

- S390 architecture;

- x86 architecture;

- Block layer subsystem;

- Compute Acceleration Framework;

- Accessibility subsystem;

- Android drivers;

- Drivers core;

- Bluetooth drivers;

- Clock framework and drivers;

- Data acquisition framework and drivers;

- Cryptographic API;

- Buffer Sharing and Synchronization framework;

- GPU drivers;

- On-Chip Interconnect managem...

Update Instructions

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

Ubuntu 24.04 LTS
  linux-image-6.8.0-1008-oracle   6.8.0-1008.8
  linux-image-6.8.0-1008-oracle-64k  6.8.0-1008.8
  linux-image-oracle              6.8.0-1008.8
  linux-image-oracle-64k          6.8.0-1008.8

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.
