The SUSE Linux Enterprise 12 SP2 kernel was updated to 4.4.114 to receive various security and bugfixes. The following security bugs were fixed: - CVE-2017-5715: Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis (bnc#1068032). The previous fix using CPU Microcode has been complemented by building the Linux Kernel with return trampolines aka 'retpolines'. - CVE-2017-15129: A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel The function get_net_ns_by_id() in net/core/net_namespace.c did not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely (bnc#1074839). - CVE-2017-17712: The raw_sendmsg() function in net/ipv4/raw.c in the Linux kernel has a race condition in inet->hdrincl that leads to uninitialized stack pointer usage; this allowed a local user to execute code and gain privileges (bnc#1073229). - CVE-2017-17862: kernel/bpf/verifier.c in the Linux kernel ignored unreachable code, even though it would still be processed by JIT compilers. This behavior, also considered an improper branch-pruning logic issue, could possibly be used by local users for denial of service (bnc#1073928). - CVE-2017-17864: kernel/bpf/verifier.c in the Linux kernel mishandled states_equal comparisons between the pointer data type and the UNKNOWN_VALUE data type, which allowed local users to obtain potentially sensitive address information, aka a 'pointer leak (bnc#1073928). - CVE-2017-18017: The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel allowed remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action (bnc#1074488). - CVE-2018-1000004: In the Linux kernel a race condition vulnerability existed in the sound system, this can lead to a deadlock and denial of service condition (bnc#1076017). - CVE-2018-5332: In the Linux kernel the rds_message_alloc_sgs() function did not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size function in net/rds/rdma.c) (bnc#1075621). - CVE-2018-5333: In the Linux kernel the rds_cmsg_atomic function in net/rds/rdma.c mishandled cases where page pinning fails or an invalid address is supplied, leading to an rds_atomic_free_op NULL pointer dereference (bnc#1075617). The following non-security bugs were fixed: - 8021q: fix a memory leak for VLAN 0 device (bnc#1012382). - ACPI / scan: Prefer devices without _HID/_CID for _ADR matching (bnc#1012382). - ARC: uaccess: dont use 'l' gcc inline asm constraint modifier (bnc#1012382). - Fix EX_SIZE. We do not have the patches that shave off parts of the exception data. - Fix build error in vma.c (bnc#1012382). - Fix mishandling of cases with MSR not being present (writing to MSR even though _state == -1). - Fix return value from ib[rs|pb]_enabled() - Input: trackpoint - force 3 buttons if 0 button is reported (bnc#1012382). - KVM: s390: Enable all facility bits that are known good for passthrough (bsc#1076806). - Kabi: Keep KVM stable after enable s390 wire up bpb feature (bsc#1076806). - Move RFI sysfs to a separate patch - Move the RFI debug code into separate patch. - Re-enable fixup detection by CPU type in case hypervisor call fails. - Revert 'Bluetooth: btusb: driver to enable the usb-wakeup feature' (bnc#1012382). - Revert 'Re-enable fixup detection by CPU type in case hypervisor call fails.' The firmware update is required for the existing instructions to also do the cache flush. - Revert 'arm64: alternatives: add enable parameter to conditional asm macros' (bsc#1068032). - Revert 'drm/armada: Fix compile fail' (bnc#1012382). - Revert 'drm/radeon: dont switch vt on suspend' (bnc#1012382). - Revert 'ipsec: Fix aborted xfrm policy dump crash' (kabi). - Revert 'kaiser: vmstat show NR_KAISERTABLE as nr_overhead' (kabi). - Revert 'lib/genalloc.c: make the avail variable an atomic_long_t' (kabi). - Revert 'module: Add retpoline tag to VERMAGIC' (bnc#1012382 kabi). - Revert 'netlink: add a start callback for starting a netlink dump' (kabi). - Revert 'ocfs2: should wait dio before inode lock in ocfs2_setattr()' (bnc#1012382). - Revert 's390/kbuild: enable modversions for symbols exported from asm' (bnc#1012382). - Revert 'sched/deadline: Use the revised wakeup rule for suspending constrained dl tasks' (kabi). - Revert 'scsi: libsas: align sata_device's rps_resp on a cacheline' (kabi). - Revert 'spi: SPI_FSL_DSPI should depend on HAS_DMA' (bnc#1012382). - Revert 'userfaultfd: selftest: vm: allow to build in vm/ directory' (bnc#1012382). - Revert 'x86/efi: Build our own page table structures' (bnc#1012382). - Revert 'x86/efi: Hoist page table switching code into efi_call_virt()' (bnc#1012382). - Revert 'x86/mm/pat: Ensure cpa->pfn only contains page frame numbers' (bnc#1012382). - SMB2: Fix share type handling (bnc#1074392). - Set supported_modules_check 1 (bsc#1072163). - Update patches.suse/powerpc-Secure-memory-rfi-flush-SLE12SP3.patch (bsc#1068032, bsc#1075087). - af_key: fix buffer overread in parse_exthdrs() (bnc#1012382). - af_key: fix buffer overread in verify_address_len() (bnc#1012382). - afs: Adjust mode bits processing (bnc#1012382). - afs: Connect up the CB.ProbeUuid (bnc#1012382). - afs: Fix afs_kill_pages() (bnc#1012382). - afs: Fix missing put_page() (bnc#1012382). - afs: Fix page leak in afs_write_begin() (bnc#1012382). - afs: Fix the maths in afs_fs_store_data() (bnc#1012382). - afs: Flush outstanding writes when an fd is closed (bnc#1012382). - afs: Migrate vlocation fields to 64-bit (bnc#1012382). - afs: Populate and use client modification time (bnc#1012382). - afs: Populate group ID from vnode status (bnc#1012382). - afs: Prevent callback expiry timer overflow (bnc#1012382). - alpha: fix build failures (bnc#1012382). - alsa: aloop: Fix inconsistent format due to incomplete rule (bsc#1031717). - alsa: aloop: Fix racy hw constraints adjustment (bsc#1031717). - alsa: aloop: Release cable upon open error path (bsc#1031717). - alsa: hda - Add HP ZBook 15u G3 Conexant CX20724 GPIO mute leds (bsc#1031717). - alsa: hda - Add MIC_NO_PRESENCE fixup for 2 HP machines (bsc#1031717). - alsa: hda - Add mute led support for HP EliteBook 840 G3 (bsc#1031717). - alsa: hda - Add mute led support for HP ProBook 440 G4 (bsc#1031717). - alsa: hda - Apply headphone noise quirk for another Dell XPS 13 variant (bsc#1031717). - alsa: hda - Apply the existing quirk to iMac 14,1 (bsc#1031717). - alsa: hda - Fix click noises on Samsung Ativ Book 8 (bsc#1031717). - alsa: hda - Fix headset microphone detection for ASUS N551 and N751 (bsc#1031717). - alsa: hda - Fix mic regression by ASRock mobo fixup (bsc#1031717). - alsa: hda - Fix missing COEF init for ALC225/295/299 (bsc#1031717). - alsa: hda - Fix surround output pins for ASRock B150M mobo (bsc#1031717). - alsa: hda - On-board speaker fixup on ACER Veriton (bsc#1031717). - alsa: hda - Skip Realtek SKU check for Lenovo machines (bsc#1031717). - alsa: hda - add support for docking station for HP 820 G2 (bsc#1031717). - alsa: hda - add support for docking station for HP 840 G3 (bsc#1031717). - alsa: hda - change the location for one mic on a Lenovo machine (bsc#1031717). - alsa: hda - fix headset mic detection issue on a Dell machine (bsc#1031717). - alsa: hda - fix headset mic problem for Dell machines with alc274 (bsc#1031717). - alsa: hda/realtek - ALC891 headset mode for Dell (bsc#103
