Description: The openSUSE Leap 42.1 kernel was updated to 4.1.26 to receive various security and bugfixes. The following security bugs were fixed: - CVE-2016-1583: Prevent the usage of mmap when the lower file system does not allow it. This could have lead to local privilege escalation when ecryptfs-utils was installed and /sbin/mount.ecryptfs_private was setuid (bsc#983143). - CVE-2016-4565: The InfiniBand (aka IB) stack in the Linux kernel incorrectly relies on the write system call, which allows local users to cause a denial of service (kernel memory write operation) or possibly have unspecified other impact via a uAPI interface. (bsc#979548) - CVE-2016-4805: Use-after-free vulnerability in drivers/net/ppp/ppp_generic.c in the Linux kernel allowed local users to cause a denial of service (memory corruption and system crash, or spinlock) or possibly have unspecified other impact by removing a network namespace, related to the ppp_register_net_channel and ppp_unregister_channel functions. (bsc#980371). - CVE-2016-4951: The tipc_nl_publ_dump function in net/tipc/socket.c in the Linux kernel did not verify socket existence, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a dumpit operation. (bsc#981058). - CVE-2016-5244: An information leak vulnerability in function rds_inc_info_copy of file net/rds/recv.c was fixed that might have leaked kernel stack data. (bsc#983213). - CVE-2016-4580: The x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel did not properly initialize a certain data structure, which allowed attackers to obtain sensitive information from kernel stack memory via an X.25 Call Request. (bsc#981267). - CVE-2016-0758: Tags with indefinite length could have corrupted pointers in asn1_find_indefinite_length (bsc#979867). - CVE-2016-2053: The asn1_ber_decoder function in lib/asn1_decoder.c in the Linux kernel allowed attackers to cause a denial of service (panic) via an ASN.1 BER file that lacks a public key, leading to mishandling by the public_key_verify_signature function in crypto/asymmetric_keys/public_key.c (bnc#963762). - CVE-2013-7446: Use-after-free vulnerability in net/unix/af_unix.c in the Linux kernel allowed local users to bypass intended AF_UNIX socket permissions or cause a denial of service (panic) via crafted epoll_ctl calls (bnc#955654). - CVE-2016-3134: The netfilter subsystem in the Linux kernel did not validate certain offset fields, which allowed local users to gain privileges or cause a denial of service (heap memory corruption) via an IPT_SO_SET_REPLACE setsockopt call (bnc#971126). - CVE-2016-3672: The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel did not properly randomize the legacy base address, which made it easier for local users to defeat the intended restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or setgid program, by disabling stack-consumption resource limits (bnc#974308). - CVE-2016-4482: A kernel information leak in the usbfs devio connectinfo was fixed, which could expose kernel stack memory to userspace. (bnc#978401). - CVE-2016-4485: A kernel information leak in llc was fixed (bsc#978821). - CVE-2016-4486: A kernel information leak in rtnetlink was fixed, where 4 uninitialized bytes could leak to userspace (bsc#978822). - CVE-2016-4557: A use-after-free via double-fdput in replace_map_fd_with_map_ptr() was fixed, which could allow privilege escalation (bsc#979018). - CVE-2016-4565: When the "rdma_ucm" infiniband module is loaded, local attackers could escalate their privileges (bsc#979548). - CVE-2016-4569: A kernel information leak in the ALSA timer via events via snd_timer_user_tinterrupt that could leak information to userspace was fixed (bsc#979213). - CVE-2016-4578: A kernel information leak in the ALSA timer via events that could leak information to userspace was fixed (bsc#979879). - CVE-2016-4581: If the first propogated mount copy was being a slave it could oops the kernel (bsc#979913) The following non-security bugs were fixed: - ALSA: hda - Add dock support for ThinkPad X260 (boo#979278). - ALSA: hda - Apply fix for white noise on Asus N550JV, too (boo#979278). - ALSA: hda - Asus N750JV external subwoofer fixup (boo#979278). - ALSA: hda - Fix broken reconfig (boo#979278). - ALSA: hda - Fix headphone mic input on a few Dell ALC293 machines (boo#979278). - ALSA: hda - Fix subwoofer pin on ASUS N751 and N551 (boo#979278). - ALSA: hda - Fix white noise on Asus N750JV headphone (boo#979278). - ALSA: hda - Fix white noise on Asus UX501VW headset (boo#979278). - ALSA: hda/realtek - Add ALC3234 headset mode for Optiplex 9020m (boo#979278). - ALSA: hda/realtek - New codecs support for ALC234/ALC274/ALC294 (boo#979278). - ALSA: hda/realtek - New codec support of ALC225 (boo#979278). - ALSA: hda/realtek - Support headset mode for ALC225 (boo#979278). - ALSA: pcxhr: Fix missing mutex unlock (boo#979278). - ALSA: usb-audio: Quirk for yet another Phoenix Audio devices (v2) (boo#979278). - bluetooth: fix power_on vs close race (bsc#966849). - bluetooth: vhci: fix open_timeout vs. hdev race (bsc#971799,bsc#966849). - bluetooth: vhci: Fix race at creating hci device (bsc#971799,bsc#966849). - bluetooth: vhci: purge unhandled skbs (bsc#971799,bsc#966849). - btrfs: do not use src fd for printk (bsc#980348). - btrfs: fix crash/invalid memory access on fsync when using overlayfs (bsc#977198) - drm: qxl: Workaround for buggy user-space (bsc#981344). - enic: set netdev->vlan_features (bsc#966245). - fs: add file_dentry() (bsc#977198). - IB/IPoIB: Do not set skb truesize since using one linearskb (bsc#980657). - input: i8042 - lower log level for "no controller" message (bsc#945345). - kabi: Add kabi/severities entries to ignore sound/hda/*, x509_*, efivar_validate, file_open_root and dax_fault - kabi: Add some fixups (module, pci_dev, drm, fuse and thermal) - kabi: file_dentry changes (bsc#977198). - kABI fixes for 4.1.22 - mm/page_alloc.c: calculate 'available' memory in a separate function (bsc#982239). - net: disable fragment reassembly if high_thresh is zero (bsc#970506). - of: iommu: Silence misleading warning. - pstore_register() error handling was wrong -- it tried to release lock before it's acquired, causing spinlock / preemption imbalance. - usb: quirk to stop runtime PM for Intel 7260 (bnc#984460). - Revert "usb: hub: do not clear BOS field during reset device" (boo#979728). - usb: core: hub: hub_port_init lock controller instead of bus (bnc#978073). - usb: preserve kABI in address0 locking (bnc#978073). - usb: usbip: fix potential out-of-bounds write (bnc#975945). - USB: xhci: Add broken streams quirk for Frescologic device id 1009 (bnc#982712). - virtio_balloon: do not change memory amount visible via /proc/meminfo (bsc#982238). - virtio_balloon: export 'available' memory to balloon statistics (bsc#982239).
