linux-raspi vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 24.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- 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:
- Ext4 file system;
- Packet sockets;
- Network traffic control;
- TLS protocol;
- VMware vSockets driver;
- XFRM subsystem;
(CVE-2025-37756, CVE-2025-38500, CVE-2025-37785, CVE-2025-38477,
CVE-2025-38618, CVE-2025-38617)

Update instructions:

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

Ubuntu 24.04 LTS
linux-image-6.8.0-1040-raspi 6.8.0-1040.44
linux-image-raspi 6.8.0-1040.44
linux-image-raspi-6.8 6.8.0-1040.44

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.
