The following security bugs were fixed:

CVE-2023-2269: Fixed a denial-of-service problem due to a possible recursive locking scenario, resulting in a deadlock in table_clear in drivers/md/dm-ioctl.c (bsc#1210806).
CVE-2022-3566: Fixed race condition in the TCP Handler (bsc#1204405).
CVE-2022-45886: Fixed a .disconnect versus dvb_device_open race condition in dvb_net.c that lead to a use-after-free (bsc#1205760).
CVE-2022-45885: Fixed a race condition in dvb_frontend.c that could cause a use-after-free when a device is disconnected (bsc#1205758).
CVE-2022-45887: Fixed a memory leak in ttusb_dec.c caused by the lack of a dvb_frontend_detach call (bsc#1205762).
CVE-2022-45919: Fixed a use-after-free in dvb_ca_en50221.c that could occur if there is a disconnect after an open, because of the lack of a wait_event (bsc#1205803).
CVE-2022-45884: Fixed a use-after-free in dvbdev.c, related to dvb_register_device dynamically allocating fops (bsc#1205756).
CVE-2023-31084: Fixed a blocking issue in drivers/media/dvb-core/dvb_frontend.c (bsc#1210783).
CVE-2023-31436: Fixed an out-of-bounds write in qfq_change_class() because lmax can exceed QFQ_MIN_LMAX (bsc#1210940).
CVE-2023-2194: Fixed an out-of-bounds write vulnerability in the SLIMpro I2C device driver (bsc#1210715).
CVE-2023-32269: Fixed a use-after-free in af_netrom.c, related to the fact that accept() was also allowed for a successfully connected AF_NETROM socket (bsc#1211186).
CVE-2023-28466: Fixed race condition that could lead to use-after-free or NULL pointer dereference in do_tls_getsockopt in net/tls/tls_main.c (bsc#1209366).
CVE-2023-1380: Fixed a slab-out-of-bound read problem in brcmf_get_assoc_ies() (bsc#1209287).
CVE-2023-2513: Fixed a use-after-free vulnerability in the ext4 filesystem (bsc#1211105).
