Details:
It was discovered that the Upper Level Protocol (ULP) subsystem in the
Linux kernel did not properly handle sockets entering the LISTEN state in
certain protocols, leading to a use-after-free vulnerability. A local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2023-0461)
Kyle Zeng discovered that the sysctl implementation in the Linux kernel
contained a stack-based buffer overflow. A local attacker could use this to
cause a denial of service (system crash) or execute arbitrary code.
(CVE-2022-4378)
It was discovered that the NVMe driver in the Linux kernel did not properly
handle reset events in some situations. A local attacker could use this to
cause a denial of service (system crash). (CVE-2022-3169)
It was discovered that a use-after-free vulnerability existed in the SGI
GRU driver in the Linux kernel. A local attacker could possibly use this to
cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2022-3424)
Gwangun Jung discovered a race condition in the IPv4 implementation in the
Linux kernel when deleting multipath routes, resulting in an out-of-bounds
read. An attacker could use this to cause a denial of service (system
crash) or possibly expose sensitive information (kernel memory).
(CVE-2022-3435)
It was discovered that a race condition existed in the Kernel Connection
Multiplexor (KCM) socket implementation in the Linux kernel when releasing
sockets in certain situations. A local attacker could use this to cause a
denial of service (system crash). (CVE-2022-3521)
It was discovered that the Netronome Ethernet driver in the Linux kernel
contained a use-after-free vulnerability. A local attacker could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2022-3545)
It was discovered that the hugetlb implementation in the Linux kernel
contained a race condition in some situations. A local attacker could use
this to cause a denial of service (system crash) or expose sensitive
information (kernel memory). (CVE-2022-3623)
Ziming Zhang discovered that the VMware Virtual GPU DRM driver in the Linux
kernel contained an out-of-bounds write vulnerability. A local attacker
could use this to cause a denial of service (system crash).
(CVE-2022-36280)
Hyunwoo Kim discovered that the DVB Core driver in the Linux kernel did not
properly perform reference counting in some situations, leading to a use-
after-free vulnerability. A local attacker could use this to cause a denial
of service (system crash) or possibly execute arbitrary code.
(CVE-2022-41218)
It was discovered that the Intel i915 graphics driver in the Linux kernel
did not perform a GPU TLB flush in some situations. A local attacker could
use this to cause a denial of service or possibly execute arbitrary code.
(CVE-2022-4139)
It was discovered that a race condition existed in the Xen network backend
driver in the Linux kernel when handling dropped packets in certain
circumstances. An attacker could use this to cause a denial of service
(kernel deadlock). (CVE-2022-42328, CVE-2022-42329)
It was discovered that the Atmel WILC1000 driver in the Linux kernel did
not properly validate offsets, leading to an out-of-bounds read
vulnerability. An attacker could use this to cause a denial of service
(system crash). (CVE-2022-47520)
It was discovered that the network queuing discipline implementation in the
Linux kernel contained a null pointer dereference in some situations. A
local attacker could use this to cause a denial of service (system crash).
(CVE-2022-47929)
José Oliveira and Rodrigo Branco discovered that the prctl syscall
implementation in the Linux kernel did not properly protect against
indirect branch prediction attacks in some situations. A local attacker
could possibly use this to expose sensitive information. (CVE-2023-0045)
It was discovered that a use-after-free vulnerability existed in the
Advanced Linux Sound Architecture (ALSA) subsystem. A local attacker could
use this to cause a denial of service (system crash). (CVE-2023-0266)
Kyle Zeng discovered that the IPv6 implementation in the Linux kernel
contained a NULL pointer dereference vulnerability in certain situations. A
local attacker could use this to cause a denial of service (system crash).
(CVE-2023-0394)
It was discovered that the Android Binder IPC subsystem in the Linux kernel
did not properly validate inputs in some situations, leading to a use-
after-free vulnerability. A local attacker could use this to cause a denial
of service (system crash) or possibly execute arbitrary code.
(CVE-2023-20938)
Kyle Zeng discovered that the class-based queuing discipline implementation
in the Linux kernel contained a type confusion vulnerability in some
situations. An attacker could use this to cause a denial of service (system
crash). (CVE-2023-23454)
Kyle Zeng discovered that the ATM VC queuing discipline implementation in
the Linux kernel contained a type confusion vulnerability in some
situations. An attacker could use this to cause a denial of service (system
crash). (CVE-2023-23455)

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.
