  <description>
The openSUSE Leap 42.1 kernel to 4.1.38 to receive various security and bugfixes.

The following security bugs were fixed:

- CVE-2016-7117: Use-after-free vulnerability in the __sys_recvmmsg function in net/socket.c in the Linux kernel allowed remote attackers to execute arbitrary code via vectors involving a recvmmsg system call that is mishandled during error processing (bnc#1003077).
- CVE-2017-5551: tmpfs: Fixed a bug that could have allowed users to set setgid bits on files they don't down (bsc#1021258).
- CVE-2016-10147: crypto/mcryptd.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) by using an AF_ALG socket with an incompatible algorithm, as demonstrated by mcryptd(md5) (bnc#1020381).
- CVE-2016-10088: The sg implementation in the Linux kernel did not properly restrict write operations in situations where the KERNEL_DS option is set, which allowed local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c.  NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576 (bnc#1017710).
- CVE-2016-7917: The nfnetlink_rcv_batch function in net/netfilter/nfnetlink.c in the Linux kernel did not check whether a batch message's length field is large enough, which allowed local users to obtain sensitive information from kernel memory or cause a denial of service (infinite loop or out-of-bounds read) by leveraging the CAP_NET_ADMIN capability (bnc#1010444).
- CVE-2016-8645: The TCP stack in the Linux kernel mishandled skb truncation, which allowed local users to cause a denial of service (system crash) via a crafted application that made sendto system calls, related to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c (bnc#1009969).
- CVE-2016-9806: Race condition in the netlink_dump function in net/netlink/af_netlink.c in the Linux kernel allowed local users to cause a denial of service (double free) or possibly have unspecified other impact via a crafted application that made sendmsg system calls, leading to a free operation associated with a new dump that started earlier than anticipated (bnc#1013540 1017589).
- CVE-2016-9793: The sock_setsockopt function in net/core/sock.c in the Linux kernel mishandled negative values of sk_sndbuf and sk_rcvbuf, which allowed local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option (bnc#1013531 1013542).

The following non-security bugs were fixed:

- PCI: generic: Fix pci_remap_iospace() failure path (bsc#1019658).
- bcache: partition support: add 16 minors per bcacheN device (bsc#1019784).
- bnx2x: Correct ringparam estimate when DOWN (bsc#1020214).
- clk: xgene: Do not call __pa on ioremaped address (bsc#1019660).
- kABI workaround for 4.1.37 mount changes (stable-4.1.37).
- kABI: reintroduce sk_filter (bsc#1009969).
- kabi/severities: Ignore inode_change_ok change It's renamed in 4.1.37 to setattr_prepare()
- mpi: Fix NULL ptr dereference in mpi_powm() [ver #3] (bsc#1011820).
- net: introduce __sock_queue_rcv_skb() function (bsc#1009969).
- netback: correct array index (bsc#983348).
- netfront: do not truncate grant references.
- netfront: use correct linear area after linearizing an skb (bsc#1007886).
- reiserfs: fix race in prealloc discard (bsc#987576).
- rose: limit sk_filter trim to payload (bsc#1009969).
- scsi: bfa: Increase requested firmware version to 3.2.5.1 (bsc#1013273).
- xenbus: correctly signal errors from xenstored_local_init() (luckily none so far).
- xenbus: do not invoke -&gt;is_ready() for most device states (bsc#987333).
