Description

Security update for the Linux Kernel The SUSE Linux Enterprise 15 SP1 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - 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-2023-20569: 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-2023-34319: Fixed buffer overrun triggered by unusual packet in xen/netback (XSA-432) (bsc#1213546). - 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-2023-3609: Fixed reference counter leak leading to overflow in net/sched (bsc#1213586). - 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). - CVE-2023-4133: Fixed use after free bugs caused by circular dependency problem in cxgb4 (bsc#1213970). - CVE-2023-4194: Fixed a type confusion in net tun_chr_open() bsc#1214019). The following non-security bugs were fixed: - arm: spear: do not use timer namespace for timer_shutdown() function (bsc#1213970). - clocksource/drivers/arm_arch_timer: do not use timer namespace for timer_shutdown() function (bsc#1213970). - clocksource/drivers/sp804: do not use timer namespace for timer_shutdown() function (bsc#1213970). - cpufeatures: allow adding more cpuid words - get module prefix from kmod (bsc#1212835). - kernel-binary.spec.in: remove superfluous %% in supplements fixes: 02b7735e0caf ('rpm/kernel-binary.spec.in: add enhances and supplements tags to in-tree kmps') - kernel-docs: add buildrequires on python3-base when using python3 the python3 binary is provided by python3-base. - kernel-docs: use python3 together with python3-sphinx (bsc#1212741). - keys: change keyring_serialise_link_sem to a mutex (bsc#1207088). - keys: fix linking a duplicate key to a keyring's assoc_array (bsc#1207088). - keys: hoist locking out of __key_link_begin() (bsc#1207088). - net/sched: sch_qfq: refactor parsing of netlink parameters (bsc#1213585). - net: mana: add support for vlan tagging (bsc#1212301). - readme.branch: add myself as co-maintainer - remove more packaging cruft for sle < 12 sp3 - rpm/check-for-config-changes: ignore also pahole_has_* we now also have options like config_pahole_has_lang_exclude. - rpm/check-for-config-changes: ignore also riscv_isa_* and dynamic_sigframe they depend on config_toolchain_has_*. - timers: add shutdown mechanism to the internal functions (bsc#1213970). - timers: provide timer_shutdown[_sync]() (bsc#1213970). - timers: rename del_timer() to timer_delete() (bsc#1213970). - timers: rename del_timer_sync() to timer_delete_sync() (bsc#1213970). - timers: replace bug_on()s (bsc#1213970). - timers: silently ignore timers with a null function (bsc#1213970). - timers: split [try_to_]del_timer[_sync]() to prepare for shutdown mode (bsc#1213970). - timers: update kernel-doc for various functions (bsc#1213970). - timers: use del_timer_sync() even on up (bsc#1213970). - ubi: ensure that vid header offset + vid header size <= alloc, size (bsc#1210584). - ubi: fix failure attaching when vid_hdr offset equals to (sub)page size (bsc#1210584). - usrmerge: Adjust module path in the kernel sources (bsc#1212835).
