The following security bugs were fixed:

CVE-2023-2162: Fixed an use-after-free flaw in iscsi_sw_tcp_session_create (bsc#1210647).
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-2023-1989: Fixed a use after free in btsdio_remove (bsc#1210336).
CVE-2017-5753: Fixed spectre vulnerability in prlimit (bsc#1209256).
CVE-2023-1670: Fixed a use after free in the Xircom 16-bit PCMCIA Ethernet driver. A local user could use this flaw to crash the system or potentially escalate their privileges on the system (bsc#1209871).
CVE-2023-1513: Fixed an uninitialized portions of the kvm_debugregs structure that could be copied to userspace, causing an information leak (bsc#1209532).
CVE-2023-28328: Fixed a denial of service issue in az6027 driver in drivers/media/usb/dev-usb/az6027.c (bsc#1209291).
CVE-2023-0590: Fixed race condition in qdisc_graft() (bsc#1207795).
CVE-2018-9517: Fixed possible memory corruption due to a use after free in pppol2tp_connect (bsc#1108488).
CVE-2023-1118: Fixed a use-after-free bugs caused by ene_tx_irqsim() in media/rc (bsc#1208837).
CVE-2023-23559: Fixed integer overflow in rndis_wlan that leads to a buffer overflow (bsc#1207051).
CVE-2023-23454: Fixed a type-confusion in the CBQ network scheduler (bsc#1207036).
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-2022-3567: Fixed a to race condition in inet6_stream_ops()/inet6_dgram_ops() (bsc#1204414).

The following non-security bugs were fixed:

Do not sign the vanilla kernel (bsc#1209008).
do not fallthrough in cbq_classify and stop on TC_ACT_SHOT");
