"The openSUSE Leap 42.2 kernel was updated to 4.4.49 to receive various
security and bugfixes.

The following security bugs were fixed :

  - CVE-2017-5986: A userlevel triggerable BUG_ON on
    sctp_wait_for_sndbuf was fixed. (bsc#1025235)

  - CVE-2017-5970: The ipv4_pktinfo_prepare function in
    net/ipv4/ip_sockglue.c in the Linux kernel allowed
    attackers to cause a denial of service (system crash)
    via (1) an application that made crafted system calls or
    possibly (2) IPv4 traffic with invalid IP options
    (bnc#1024938).

  - CVE-2017-5897: A potential remote denial of service
    within the IPv6 GRE protocol was fixed. (bsc#1023762)

  - CVE-2017-6074: The dccp_rcv_state_process function in
    net/dccp/input.c in the Linux kernel mishandled
    DCCP_PKT_REQUEST packet data structures in the LISTEN
    state, which allowed local users to cause a denial of
    service (invalid free) or possibly have unspecified
    other impact via an application that makes an
    IPV6_RECVPKTINFO setsockopt system call. (bsc#1026024).

The following non-security bugs were fixed :

  - btrfs: fix btrfs_compat_ioctl failures on non-compat
    ioctls (bsc#1018100).

  - iwlwifi: Expose the default fallback ucode API to module
    info (boo#1021082, boo#1023884).

  - kabi: protect struct tcp_fastopen_cookie (kabi).

  - md: ensure md devices are freed before module is
    unloaded (bsc#1022304).

  - md: Fix a regression reported by bsc#1020048 in
    patches.fixes/0003-md-lockless-I-O-submission-for-RAID1.
    patch (bsc#982783,bsc#998106,bsc#1020048).

  - net: ethtool: Initialize buffer when querying device
    channel settings (bsc#969479 FATE#320634).

  - net: implement netif_cond_dbg macro (bsc#1019168).

  - sfc: reduce severity of PIO buffer alloc failures
    (bsc#1019168).

  - sfc: refactor debug-or-warnings printks (bsc#1019168).

  - xfs_dmapi: fix the debug compilation of xfs_dmapi
    (bsc#989056).

  - xfs: do not allow di_size with high bit set
    (bsc#1024234).

  - xfs: exclude never-released buffers from buftarg I/O
    accounting (bsc#1024508).

  - xfs: fix broken multi-fsb buffer logging (bsc#1024081).

  - xfs: fix buffer overflow
    dm_get_dirattrs/dm_get_dirattrs2 (bsc#989056).

  - xfs: fix up xfs_swap_extent_forks inline extent handling
    (bsc#1023888).

  - xfs: track and serialize in-flight async buffers against
    unmount (bsc#1024508).

  - xfs: track and serialize in-flight async buffers against
    unmount - kABI (bsc#1024508)."
