The openSUSE 13.2 kernel was updated to receive various security and bugfixes.

Following security bugs were fixed: * CVE-2015-3290: arch/x86/entry/entry_64.S in the Linux kernel on the x86_64 platform improperly relied on espfix64 during nested NMI processing, which allowed local users to gain privileges by triggering an NMI within a certain instruction window (bnc#937969) * CVE-2015-0272: It was reported that it's possible to craft a Router Advertisement message which will bring the receiver in a state where new IPv6 connections will not be accepted until correct Router Advertisement message received. (bsc#944296). * CVE-2015-5283: The sctp_init function in net/sctp/protocol.c in the Linux kernel had an incorrect sequence of protocol-initialization steps, which allowed local users to cause a denial of service (panic or memory corruption) by creating SCTP sockets before all of the steps have finished (bnc#947155). * CVE-2015-1333: Memory leak in the __key_link_end function in security/keys/keyring.c in the Linux kernel allowed local users to cause a denial of service (memory consumption) via many add_key system calls that refer to existing keys. (bsc#938645) * CVE-2015-5707: Integer overflow in the sg_start_req function in drivers/scsi/sg.c in the Linux kernel allowed local users to cause a denial of service or possibly have unspecified other impact via a large iov_count value in a write request. (bsc#940338) * CVE-2015-2925: An attacker could potentially break out of a namespace or container, depending on if he had specific rights in these containers. (bsc#926238). * CVE-2015-7872: A vulnerability in keyrings garbage collector allowed a local user to trigger an oops was found, caused by using request_key() or keyctl request2. (bsc#951440)

The following non-security bugs were fixed: - input: evdev - do not report errors form flush() (bsc#939834). - NFSv4: Recovery of recalled read delegations is broken (bsc#942178). - apparmor: temporary work around for bug while unloading policy (boo#941867). - config/x86_64/ec2: Align CONFIG_STRICT_DEVMEM CONFIG_STRICT_DEVMEM is enabled in every other kernel flavor, so enable it for x86_64/ec2 as well. - kernel-obs-build: add btrfs to initrd This is needed for kiwi builds. - mmc: card: Do not access RPMB partitions for normal read/write (bnc#941104). - netback: coalesce (guest) RX SKBs as needed (bsc#919154). - rpm/ Add virtio_rng to the initrd. This allows to feed some randomness to the OBS workers. - xfs: Fix file type directory corruption for btree directories (bsc#941305). - xfs: ensure buffer types are set correctly (bsc#941305). - xfs: inode unlink does not set AGI buffer type (bsc#941305). - xfs: set buf types when converting extent formats (bsc#941305). - xfs: set superblock buffer type correctly (bsc#941305). - xhci: Add spurious wakeup quirk for LynxPoint-LP controllers (bnc#951195).
