The SUSE Linux Enterprise 15 SP5 RT kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
CVE-2022-38457: Fixed a use-after-free vulnerability in vmwgfx driver that allowed a local attacker to cause a denial of service (bsc#1203330).
CVE-2022-40133: Fixed a use-after-free vulnerability in vmwgfx driver that allowed a local attacker to cause a denial of service (bsc#1203329).
CVE-2023-2007: Fixed a flaw in the DPT I2O Controller driver that could allow an attacker to escalate privileges and execute arbitrary code in the context of the kernel (bsc#1210448).
CVE-2023-3610: Fixed use-after-free vulnerability in nf_tables can be exploited to achieve local privilege escalation (bsc#1213580).
CVE-2023-3772: Fixed a flaw in XFRM subsystem that may have allowed a malicious user with CAPNETADMIN privileges to directly dereference a NULL pointer leading to a possible kernel crash and denial of service (bsc#1213666).
CVE-2023-3863: Fixed a use-after-free flaw was found in nfcllcpfind_local that allowed a local user with special privileges to impact a kernel information leak issue (bsc#1213601).

CVE-2023-4128: Fixed a use-after-free flaw in net/sched/cls_fw.c that allowed a local attacker to perform a local privilege escalation due to incorrect handling of the existing filter, leading to a kernel information leak issue (bsc#1214149).
CVE-2023-4133: Fixed use after free bugs caused by circular dependency problem in cxgb4 (bsc#1213970).
CVE-2023-4134: Fixed use-after-free in cyttsp4watchdogwork() (bsc#1213971).

CVE-2023-4194: Fixed a type confusion in net tunchropen() (bsc#1214019).
CVE-2023-4273: Fixed a flaw in the exFAT driver of the Linux kernel that alloawed a local privileged attacker to overflow the kernel stack (bsc#1214120).
CVE-2023-4387: Fixed use-after-free flaw in vmxnet3rqallocrxbuf that could allow a local attacker to crash the system due to a double-free (bsc#1214350).
CVE-2023-4459: Fixed a NULL pointer dereference flaw in vmxnet3rqcleanup that may have allowed a local attacker with normal user privilege to cause a denial of service (bsc#1214451).
CVE-2023-4563: Fixed use-after-free in nftverdictdump due to a race between set GC and transaction (bsc#1214727).
CVE-2023-4569: Fixed information leak in nftsetcatchallflush in net/netfilter/nftables_api.c (bsc#1214729).
CVE-2023-20588: Fixed a division-by-zero error on some AMD processors that can potentially return speculative data resulting in loss of confidentiality (bsc#1213927).
CVE-2023-34319: Fixed buffer overrun triggered by unusual packet in xen/netback (XSA-432) (bsc#1213546).
CVE-2023-37453: Fixed oversight in SuperSpeed initialization (bsc#1213123).
The following non-security bugs were fixed:
ACPI/IORT: Update SMMUv3 DeviceID support (bsc#1214305).
ACPI: processor: perflib: Avoid updating frequency QoS unnecessarily (git-fixes).
ACPI: processor: perflib: Use the 'no limit' frequency QoS (git-fixes).
Bluetooth: btusb: Add MT7922 bluetooth ID for the Asus Ally (git-fixes).
Bluetooth: btusb: Do not call kfreeskb() under spinlock_irqsave() (git-fixes).
Bluetooth: nokia: fix value check in nokiabluetoothserdev_probe() (git-fixes).
CONFIGNVMEVERBOSE_ERRORS=y gone with a82baa8083b
CONFIGPRINTKSAFELOGBUF_SHIFT=13 gone with 7e152d55123
Created new preempt kernel flavor Configs are cloned from the respective $arch/default configs. All changed configs appart from CONFIGPREEMPT->y are a result of dependencies, namely many lock/unlock primitives are no longer inlined in the preempt kernel. TREERCU has been also changed to PREEMPT_RCU which is the default implementation for PREEMPT kernel.
