The following security bugs were fixed:

CVE-2023-23455: Fixed a denial of service inside atm_tc_enqueue in
 net/sched/sch_atm.c because of type confusion (non-negative numbers can
 sometimes indicate a TC_ACT_SHOT condition rather than valid
 classification results) (bsc#1207125).

CVE-2023-23454: Fixed denial or service in cbq_classify in
 net/sched/sch_cbq.c (bnc#1207036).

CVE-2023-0590: Fixed race condition in qdisc_graft() (bsc#1207795).

CVE-2023-0266: Fixed a use-after-free vulnerability inside the ALSA PCM
 package. SNDRV_CTL_IOCTL_ELEM_{READ<pipe>WRITE}32 was missing locks that
 could have been used in a use-after-free that could have resulted in a
 priviledge escalation to gain ring0 access from the system user
 (bsc#1207134).

CVE-2023-0179: Fixed incorrect arithmetics when fetching VLAN header
 bits (bsc#1207034).

CVE-2023-0122: Fixed a NULL pointer dereference vulnerability in
 nvmet_setup_auth(), that allowed an attacker to perform a Pre-Auth
 Denial of Service (DoS) attack on a remote machine (bnc#1207050).

CVE-2022-4382: Fixed a use-after-free flaw that was caused by a race
 condition among the superblock operations inside the gadgetfs code
 (bsc#1206258).

CVE-2020-24588: Fixed injection of arbitrary network packets against
 devices that support receiving non-SSP A-MSDU frames (which is mandatory
 as part of 802.11n) (bsc#1199701).

The following non-security bugs were fixed:

ACPI: EC: Fix EC address space handler unregistration (bsc#1207149).

ACPI: EC: Fix ECDT probe ordering issues (bsc#1207149).

ACPI: PRM: Check whether EFI runtime is available (git-fixes).

ACPICA: Allow address_space_handler Install and _REG execution as 2
 separate steps (bsc#1207149).

ACPICA: include/acpi/acpixf.h: Fix indentation (bsc#1207149).

ALSA: control-led: use strscpy in set_led_id() (git-fixes).

ALSA: hda - Enable headset mic on another Dell laptop with ALC3254
 (git-fixes).

ALSA: hda/hdmi: Add a HP device 0x8715 to force connect list (git-fixes).

ALSA: hda/realtek - Turn on power early (git-fixes).

ALSA: hda/realtek: Add Acer Predator PH315-54 (git-fixes).

ALSA: hda/realtek: Enable mute/micmute LEDs on HP Spectre x360 13-aw0xxx
 (git-fixes).

ALSA: hda/realtek: fix mute/micmute LEDs do not work for a HP platform
 (git-fixes).

ALSA: hda/realtek: fix mute/micmute LEDs for a HP ProBook (git-fixes).

ALSA: hda/realtek: fix mute/micmute LEDs, speaker do not work for a HP
 platform (git-fixes).

ALSA: hda/via: Avoid potential array out-of-bound in
 add_secret_dac_path() (git-fixes).

ALSA: hda: cs35l41: Check runtime suspend capability at runtime_idle
 (git-fixes).

ALSA: hda: cs35l41: Do not return -EINVAL from system suspend/resume
 (git-fixes).

ALSA: pcm: Move rwsem lock inside snd_ctl_elem_read to prevent UAF
 (git-fixes).

ALSA: usb-audio: Make sure to stop ... [Please see the references for more information on the vulnerabilities]");
