a denial of service (NULL pointer dereference and OOPS) via a
request_key system call for the “dead” type. (bsc#1029850).
– CVE-2017-2647: The KEYS subsystem in the Linux kernel allowed local
users to gain privileges or cause a denial of service (NULL pointer
dereference and system crash) via vectors involving a NULL value for a
certain match field, related to the keyring_search_iterator function in
keyring.c. (bsc#1030593)
– CVE-2016-9604: This fixes handling of keyrings starting with ‘.’ in
KEYCTL_JOIN_SESSION_KEYRING, which could have allowed local users to
manipulate privileged keyrings (bsc#1035576)
– CVE-2017-7616: Incorrect error handling in the set_mempolicy and mbind
compat syscalls in mm/mempolicy.c in the Linux kernel allowed local
users to obtain sensitive information from uninitialized stack data by
triggering failure of a certain bitmap operation. (bnc#1033336).
– CVE-2017-7645: The NFSv2/NFSv3 server in the nfsd subsystem in the Linux
kernel allowed remote attackers to cause a denial of service (system
crash) via a long RPC reply, related to net/sunrpc/svc.c,

the Linux kernel did not properly validate certain block-size data,
which allowed local users to cause a denial of service (overflow) or
possibly have unspecified other impact via crafted system calls
(bnc#1031579)
– CVE-2017-2671: The ping_unhash function in net/ipv4/ping.c in the Linux
kernel was too late in obtaining a certain lock and consequently could
not ensure that disconnect function calls are safe, which allowed local
users to cause a denial of service (panic) by leveraging access to the
protocol value of IPPROTO_ICMP in a socket system call (bnc#1031003)
– CVE-2017-7294: The vmw_surface_define_ioctl function in
drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not
validate addition of certain levels data, which allowed local users to

– CVE-2016-9588: arch/x86/kvm/vmx.c in the Linux kernel mismanaged the #BP
and #OF exceptions, which allowed guest OS users to cause a denial of
service (guest OS crash) by declining to handle an exception thrown by
an L2 guest (bsc#1015703).
– CVE-2017-5669: The do_shmat function in ipc/shm.c in the Linux kernel
did not restrict the address calculated by a certain rounding operation,
which allowed local users to map page zero, and consequently bypass a
protection mechanism that exists for the mmap system call, by making
crafted shmget and shmat system calls in a privileged context
(bnc#1026914).
– CVE-2016-10200: Race condition in the L2TPv3 IP Encapsulation feature in
the Linux kernel allowed local users to gain privileges or cause a
denial of service (use-after-free) by making multiple bind system calls
without properly ascertaining whether a socket has the SOCK_ZAPPED
status, related to net/l2tp/l2tp_ip.c and net/l2tp/l2tp_ip6.c
(bnc#1028415)
– CVE-2016-10208: The ext4_fill_super function in fs/ext4/super.c in the

physically proximate attackers to cause a denial of service
(out-of-bounds read and system crash) via a crafted ext4 image
(bnc#1023377).
– CVE-2017-5897: The ip6gre_err function in net/ipv6/ip6_gre.c in the
Linux kernel allowed remote attackers to have unspecified impact via
vectors involving GRE flags in an IPv6 packet, which trigger an
out-of-bounds access (bsc#1023762).
– CVE-2017-5986: A race condition in the sctp_wait_for_sndbuf function in
net/sctp/socket.c in the Linux kernel allowed local users to cause a
denial of service (assertion failure and panic) via a multithreaded
application that peels off an association in a certain buffer-full state
(bsc#1025235).
– 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 obtain root privileges
or cause a denial of service (double free) via an application that made
an IPV6_RECVPKTINFO setsockopt system call (bnc#1026024)
– CVE-2016-9191: The cgroup offline implementation in the Linux kernel
mishandled certain drain operations, which allowed local users to cause
a denial of service (system hang) by leveraging access to a container
environment for executing a crafted application (bnc#1008842)

Linux kernel improperly managed lock dropping, which allowed local users
to cause a denial of service (deadlock) via crafted operations on IrDA
devices (bnc#1027178).
– CVE-2016-10044: The aio_mount function in fs/aio.c in the Linux kernel
did not properly restrict execute access, which made it easier for local
users to bypass intended SELinux W^X policy restrictions, and
consequently gain privileges, via an io_setup system call (bnc#1023992).
– CVE-2016-3070: The trace_writeback_dirty_page implementation in
include/trace/events/writeback.h in the Linux kernel improperly
interacts with mm/migrate.c, which allowed local users to cause a denial
of service (NULL pointer dereference and system crash) or possibly have
unspecified other impact by triggering a certain page move (bnc#979215).
– CVE-2016-5243: The tipc_nl_compat_link_dump function in
net/tipc/netlink_compat.c in the Linux kernel did not properly copy a
certain string, which allowed local users to obtain sensitive
information from kernel stack memory by reading a Netlink message
(bnc#983212).
– CVE-2017-6345: The LLC subsystem in the Linux kernel did not ensure that
a certain destructor exists in required circumstances, which allowed
local users to cause a denial of service (BUG_ON) or possibly have
unspecified other impact via crafted system calls (bnc#1027190)
– CVE-2017-6346: Race condition in net/packet/af_packet.c in the Linux
kernel allowed local users to cause a denial of service (use-after-free)
or possibly have unspecified other impact via a multithreaded
application that made PACKET_FANOUT setsockopt system calls (bnc#1027189)
– CVE-2017-6353: net/sctp/socket.c in the Linux kernel did not properly
restrict association peel-off operations during certain wait states,
which allowed local users to cause a denial of service (invalid unlock
and double free) via a multithreaded application. NOTE: this
vulnerability exists because of an incorrect fix for CVE-2017-5986
(bnc#1027066)
– CVE-2017-5986: Race condition in the sctp_wait_for_sndbuf function in
net/sctp/socket.c in the Linux kernel allowed local users to cause a
denial of service (assertion failure and panic) via a multithreaded
application that peels off an association in a certain buffer-full state
(bsc#1025235).
– CVE-2017-6214: The tcp_splice_read function in net/ipv4/tcp.c in the
Linux kernel allowed remote attackers to cause a denial of service
(infinite loop and soft lockup) via vectors involving a TCP packet with
the URG flag (bnc#1026722)
– CVE-2016-2117: The atl2_probe function in
drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel incorrectly
enables scatter/gather I/O, which allowed remote attackers to obtain
sensitive information from kernel memory by reading packet data
(bnc#968697)
– CVE-2015-1350: The VFS subsystem in the Linux kernel provided an
incomplete set of requirements for setattr operations that
underspecifies removing extended privilege attributes, which allowed
local users to cause a denial of service (capability stripping) via a
failed invocation of a system call, as demonstrated by using chown to
remove a capability from the ping or Wireshark dumpcap program
(bsc#914939).
– CVE-2016-7117: Use-after-free vulnerability in the __sys_recvmmsg
function in net/socket.c in the Linux kernel allowed remote attackers to
