The following security bugs were fixed:

CVE-2018-20784: Fixed a denial of service (infinite loop in update_blocked_averages) by mishandled leaf cfs_rq in kernel/sched/fair.c (bsc#1126703).
CVE-2018-3639: Fixed Speculative Store Bypass aka 'Memory Disambiguation' (bsc#1087082).
CVE-2022-40982: Fixed transient execution attack called 'Gather Data Sampling' (bsc#1206418).
CVE-2023-0459: Fixed information leak in __uaccess_begin_nospec (bsc#1211738).
CVE-2023-1637: Fixed vulnerability that could lead to unauthorized access to CPU memory after resuming CPU from suspend-to-RAM (bsc#1209779).
CVE-2023-20569: Fixed side channel attack 'Inception' or 'RAS Poisoning' (bsc#1213287).
CVE-2023-20593: Fixed a ZenBleed issue in 'Zen 2' CPUs that could allow an attacker to potentially access sensitive information (bsc#1213286).
CVE-2023-2985: Fixed an use-after-free vulnerability in hfsplus_put_super in fs/hfsplus/super.c that could allow a local user to cause a denial of service (bsc#1211867).
CVE-2023-3106: Fixed crash in XFRM_MSG_GETSA netlink handler (bsc#1213251).
CVE-2023-3268: Fixed an out of bounds memory access flaw in relay_file_read_start_pos in the relayfs (bsc#1212502).
CVE-2023-35001: Fixed an out-of-bounds memory access flaw in nft_byteorder that could allow a local attacker to escalate their privilege (bsc#1213059).
CVE-2023-3567: Fixed a use-after-free in vcs_read in drivers/tty/vt/vc_screen.c (bsc#1213167).
CVE-2023-3611: Fixed an out-of-bounds write in net/sched sch_qfq(bsc#1213585).
CVE-2023-3776: Fixed improper refcount update in cls_fw leads to use-after-free (bsc#1213588).

The following non-security bugs were fixed:

net/sched: sch_qfq: refactor parsing of netlink parameters (bsc#1213585).
ubi: Fix failure attaching when vid_hdr offset equals to (sub)page size (bsc#1210584).
ubi: ensure that VID header offset + VID header size &lt,= alloc, size (bsc#1210584).
x86: Treat R_X86_64_PLT32 as R_X86_64_PC32 (git-fixes) No it's not git-fixes it's used to make sle12-sp2 compile with newer toolchain to make the life of all the poor souls maintaining this ancient kernel on their modern machines, a little bit easier.");
