Details:
It was discovered that the TUN/TAP driver in the Linux kernel did not
properly initialize socket data. A local attacker could use this to cause a
denial of service (system crash). (CVE-2023-1076)
It was discovered that the Real-Time Scheduling Class implementation in the
Linux kernel contained a type confusion vulnerability in some situations. A
local attacker could use this to cause a denial of service (system crash).
(CVE-2023-1077)
It was discovered that the ASUS HID driver in the Linux kernel did not
properly handle device removal, leading to a use-after-free vulnerability.
A local attacker with physical access could plug in a specially crafted USB
device to cause a denial of service (system crash). (CVE-2023-1079)
It was discovered that the Xircom PCMCIA network device driver in the Linux
kernel did not properly handle device removal events. A physically
proximate attacker could use this to cause a denial of service (system
crash). (CVE-2023-1670)
It was discovered that a race condition existed in the Xen transport layer
implementation for the 9P file system protocol in the Linux kernel, leading
to a use-after-free vulnerability. A local attacker could use this to cause
a denial of service (guest crash) or expose sensitive information (guest
kernel memory). (CVE-2023-1859)
Jose Oliveira and Rodrigo Branco discovered that the Spectre Variant 2
mitigations with prctl syscall were insufficient in some situations. A
local attacker could possibly use this to expose sensitive information.
(CVE-2023-1998)
It was discovered that the BigBen Interactive Kids' gamepad driver in the
Linux kernel did not properly handle device removal, leading to a use-
after-free vulnerability. A local attacker with physical access could plug
in a specially crafted USB device to cause a denial of service (system
crash). (CVE-2023-25012)
It was discovered that a use-after-free vulnerability existed in the HFS+
file system implementation in the Linux kernel. A local attacker could
possibly use this to cause a denial of service (system crash).
(CVE-2023-2985)

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.
