Details
It was discovered that the JFS file system contained an out-of-bounds read
vulnerability when printing xattr debug information. A local attacker could
use this to cause a denial of service (system crash).
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:
- GPU drivers;
- Greybus drivers;
- Modular ISDN driver;
- Multiple devices driver;
- Network drivers;
- SCSI drivers;
- VFIO drivers;
- F2FS file system;
- GFS2 file system;
- JFS file system;
- NILFS2 file system;
- Kernel debugger infrastructure;
- Bluetooth subsystem;
- IPv4 networking;
- L2TP protocol;
- Netfilter;
- RxRPC session sockets;

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.
