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:
   - Block layer subsystem;
   - GPU drivers;
   - HID subsystem;
   - Media drivers;
   - JFS file system;
   - Network namespace;
   - Networking core;
   - Netlink;
(CVE-2024-57798, CVE-2024-53140, CVE-2024-56595, CVE-2024-56598,

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.
