Details:

Chenyuan Yang discovered that the RDS Protocol implementation in the Linux
kernel contained an out-of-bounds read vulnerability. An attacker could use
this to possibly cause a denial of service (system crash). (CVE-2024-23849)

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.
