Details
Daniele Antonioli discovered that the Secure Simple Pairing and Secure
Connections pairing in the Bluetooth protocol could allow an
unauthenticated user to complete authentication without pairing
credentials. A physically proximate attacker placed between two Bluetooth
devices could use this to subsequently impersonate one of the paired
devices. (CVE-2023-24023)
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:
- JFS file system;
- Netfilter;
(CVE-2024-26581, CVE-2023-52600, CVE-2023-52603)

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.
