Description: The openSUSE Leap 42.1 kernel was updated to 4.1.36 to receive various security and bugfixes. The following security bugs were fixed: - CVE-2016-8655: A race condition in the af_packet packet_set_ring function could be used by local attackers to crash the kernel or gain privileges (bsc#1012754). - CVE-2016-9794: A use-after-free in ALSA pcm could lead to crashes or allowed local users to potentially gain privileges (bsc#1013533). - CVE-2015-8962: Double free vulnerability in the sg_common_write function in drivers/scsi/sg.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (memory corruption and system crash) by detaching a device during an SG_IO ioctl call (bnc#1010501). - CVE-2016-9178: The __get_user_asm_ex macro in arch/x86/include/asm/uaccess.h in the Linux kernel did not initialize a certain integer variable, which allowed local users to obtain sensitive information from kernel stack memory by triggering failure of a get_user_ex call (bnc#1008650). - CVE-2016-7913: The xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via vectors involving omission of the firmware name from a certain data structure (bnc#1010478). - CVE-2016-9555: The sctp_sf_ootb function in net/sctp/sm_statefuns.c in the Linux kernel lacks chunk-length checking for the first chunk, which allowed remote attackers to cause a denial of service (out-of-bounds slab access) or possibly have unspecified other impact via crafted SCTP data (bnc#1011685). - CVE-2015-8963: Race condition in kernel/events/core.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) by leveraging incorrect handling of an swevent data structure during a CPU unplug operation (bnc#1010502). - CVE-2015-8964: The tty_set_termios_ldisc function in drivers/tty/tty_ldisc.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by reading a tty data structure (bnc#1010507). - CVE-2016-8646: The hash_accept function in crypto/algif_hash.c in the Linux kernel allowed local users to cause a denial of service (OOPS) by attempting to trigger use of in-kernel hash algorithms for a socket that has received zero bytes of data (bnc#1010150). - CVE-2016-8633: drivers/firewire/net.c in the Linux kernel in certain unusual hardware configurations, allowed remote attackers to execute arbitrary code via crafted fragmented packets (bnc#1008833). - CVE-2016-8630: The x86_decode_insn function in arch/x86/kvm/emulate.c in the Linux kernel, when KVM is enabled, allowed local users to cause a denial of service (host OS crash) via a certain use of a ModR/M byte in an undefined instruction (bnc#1009222). - CVE-2016-9083: drivers/vfio/pci/vfio_pci.c in the Linux kernel allowed local users to bypass integer overflow checks, and cause a denial of service (memory corruption) or have unspecified other impact, by leveraging access to a vfio PCI device file for a VFIO_DEVICE_SET_IRQS ioctl call, aka a "state machine confusion bug (bnc#1007197). - CVE-2016-9084: drivers/vfio/pci/vfio_pci_intrs.c in the Linux kernel misuses the kzalloc function, which allowed local users to cause a denial of service (integer overflow) or have unspecified other impact by leveraging access to a vfio PCI device file (bnc#1007197). - CVE-2016-7042: The proc_keys_show function in security/keys/proc.c in the Linux kernel through 4.8.2, when the GNU Compiler Collection (gcc) stack protector is enabled, uses an incorrect buffer size for certain timeout data, which allowed local users to cause a denial of service (stack memory corruption and panic) by reading the /proc/keys file (bnc#1004517). - CVE-2016-7097: The filesystem implementation in the Linux kernel preserves the setgid bit during a setxattr call, which allowed local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions (bnc#995968). - CVE-2015-8956: The rfcomm_sock_bind function in net/bluetooth/rfcomm/sock.c in the Linux kernel allowed local users to obtain sensitive information or cause a denial of service (NULL pointer dereference) via vectors involving a bind system call on a Bluetooth RFCOMM socket (bnc#1003925). The following non-security bugs were fixed: - ata: ahci_xgene: dereferencing uninitialized pointer in probe (bsc#1006580). - blacklist.conf: add some commits (bsc#1006580) - bna: Add synchronization for tx ring (bsc#993739). - bonding: set carrier off for devices created through netlink (bsc#999577). - btrfs: deal with duplicates during extent_map insertion in btrfs_get_extent (bsc#1001171). - btrfs: deal with existing encompassing extent map in btrfs_get_extent() (bsc#1001171). - btrfs: fix extent tree corruption due to relocation (bsc#990384). - btrfs: fix races on root_log_ctx lists (bsc#1007653). - ext4: fix data exposure after a crash (bsc#1012876). - ext4: fix reference counting bug on block allocation error (bsc#1012876). - gre: Disable segmentation offloads w/ CSUM and we are encapsulated via FOU (bsc#1001486). - gro: Allow tunnel stacking in the case of FOU/GUE (bsc#1001486). - ipv6: send NEWLINK on RA managed/otherconf changes (bsc#934067). - ipv6: send only one NEWLINK when RA causes changes (bsc#934067). - isofs: Do not return EACCES for unknown filesystems (bsc#1012876). - jbd2: fix checkpoint list cleanup (bsc#1012876). - jbd2: Fix unreclaimed pages after truncate in data=journal mode (bsc#1010909). - locking/static_key: Fix concurrent static_key_slow_inc() (bsc#1006580). - mmc: Fix kabi breakage of mmc-block in 4.1.36 (stable-4.1.36). - posix_acl: Added fix for f2fs. - Revert "kbuild: add -fno-PIE" (stable-4.1.36). - Revert "x86/mm: Expand the exception table logic to allow new handling options" (stable-4.1.36). - tunnels: Remove encapsulation offloads on decap (bsc#1001486). - usbhid: add ATEN CS962 to list of quirky devices (bsc#1007615). - vmxnet3: Wake queue from reset work (bsc#999907).
