The following security bugs were fixed:

CVE-2022-38096: Fixed NULL-ptr deref in vmw_cmd_dx_define_query() (bsc#1203331).
CVE-2022-4129: Fixed a denial of service with the Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing sk_user_data can lead to a race condition and NULL pointer dereference. (bsc#1205711)
CVE-2023-0597: Fixed lack of randomization of per-cpu entry area in x86/mm (bsc#1207845).
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-2023-26545: Fixed double free in net/mpls/af_mpls.c upon an allocation failure (bsc#1208700).

The following non-security bugs were fixed:

bonding: fix 802.3ad state sent to partner when unbinding slave (git-fixes).
do not sign the vanilla kernel (bsc#1209008).
icmp: do not fail on fragment reassembly time exceeded (git-fixes).
ipmi: fix initialization when workqueue allocation fails (git-fixes).
ipmi: msghandler: Make symbol 'remove_work_wq' static (git-fixes).
kabi fix for - SUNRPC: Fix priority queue fairness (git-fixes).
kabi fix for: NFS: Pass error information to the pgio error cleanup routine (git-fixes).
kabi/severities: add l2tp local symbols kernel-module-subpackage: Fix expansion with -b parameter (bsc#1208179). When -b is specified the script is prefixed with KMP_NEEDS_MKINITRD=1 which sets the variable for a simple command. However, the script is no longer a simple command. Export the variable instead.
media: coda: Add check for dcoda_iram_alloc (git-fixes).
media: coda: Add check for kmalloc (git-fixes).
media: platform: ti: Add missing check for devm_regulator_get (git-fixes).
net: aquantia: fix RSS table and key sizes (git-fixes).
netfilter: ipvs: Fix inappropriate output of procfs (git-fixes).
netfilter: xt_connlimit: do not store address in the conn nodes (git-fixes).
nfs: Fix nfsi->nrequests count error on nfs_inode_remove_request (git-fixes).
nfs: Pass error information to the pgio error cleanup routine (git-fixes).
nfsd: fix handling of readdir in v4root vs. mount upcall timeout (git-fixes).
nfsd: fix race to check ls_layouts (git-fixes).
nfsd: under NFSv4.1, fix double svc_xprt_put on rpc_create failure (git-fixes).
ocfs2: Fix data corruption after failed write (bsc#1208542).
pNFS/filelayout: Fix coalescing test for single DS (git-fixes).
powerpc/eeh: Fix use-after-release of EEH driver (bsc#1065729).
powerpc/fscr: Enable interrupts earlier before calling get_user() (bsc#1065729).
powerpc/powernv: Fix build error in opal-imc.c when NUMA=n (bsc#1065729).
powerpc/powernv: IMC fix out of bounds memory access at shutdown (bsc#1065729).
scsi: qla2xxx: Add option to disable FC2 Target support (bsc#1198438 bsc#1206103).
sunrpc: Fix priority queue fairness ... [Please see the references for more information on the vulnerabilities]");
