linux, linux-raspi, linux-realtime vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 25.10
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux: Linux kernel
- linux-raspi: Linux kernel for Raspberry Pi systems
- linux-realtime: Linux kernel for Real-time systems
Details:

Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 25.10
linux-image-6.17.0-1006-realtime 6.17.0-1006.7
linux-image-6.17.0-1008-raspi 6.17.0-1008.8
linux-image-6.17.0-14-generic 6.17.0-14.14
linux-image-6.17.0-14-generic-64k 6.17.0-14.14
linux-image-generic 6.17.0-14.14
linux-image-generic-6.17 6.17.0-14.14
linux-image-generic-64k 6.17.0-14.14
linux-image-generic-64k-6.17 6.17.0-14.14
linux-image-raspi 6.17.0-1008.8
linux-image-raspi-6.17 6.17.0-1008.8
linux-image-realtime 6.17.0-1006.7
linux-image-realtime-6.17 6.17.0-1006.7
linux-image-virtual 6.17.0-14.14
linux-image-virtual-6.17 6.17.0-14.14
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.
