"Security Fix(es) :

  - An integer overflow flaw was found in the way the Linux
    kernel's networking subsystem processed TCP Selective
    Acknowledgment (SACK) segments. While processing SACK
    segments, the Linux kernel's socket buffer (SKB) data
    structure becomes fragmented. Each fragment is about TCP
    maximum segment size (MSS) bytes. To efficiently process
    SACK blocks, the Linux kernel merges multiple fragmented
    SKBs into one, potentially overflowing the variable
    holding the number of segments. A remote attacker could
    use this flaw to crash the Linux kernel by sending a
    crafted sequence of SACK segments on a TCP connection
    with small value of TCP MSS, resulting in a denial of
    service (DoS). (CVE-2019-11477)

  - kernel: Double free in lib/idr.c (CVE-2019-3896)

  - Kernel: tcp: excessive resource consumption while
    processing SACK blocks allows remote denial of service
    (CVE-2019-11478)

  - Kernel: tcp: excessive resource consumption for TCP
    connections with low MSS allows remote denial of service
    (CVE-2019-11479)

Bug Fix(es) :

  - MDS mitigations not enabled on Intel Skylake CPUs

  - kernel does not disable SMT with mds=full,nosmt

  - md_clear flag missing from /proc/cpuinfo"

"The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.180 to
receive various security and bugfixes.

The following security bugs were fixed :

CVE-2019-11477: A sequence of SACKs may have been crafted such that
one can trigger an integer overflow, leading to a kernel panic.
(bsc#1137586)

CVE-2019-11478: It was possible to send a crafted sequence of SACKs
which will fragment the TCP retransmission queue. An attacker may have
been able to further exploit the fragmented queue to cause an
expensive linked-list walk for subsequent SACKs received for that same
TCP connection.

CVE-2019-11479: It was possible to send a crafted sequence of SACKs
which will fragment the RACK send map. A remote attacker may be able
to further exploit the fragmented send map to cause an expensive
linked-list walk for subsequent SACKs received for that same TCP
connection. This would have resulted in excess resource consumption
due to low mss values.

CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and
possibly escalate privileges was found in the mwifiex kernel module
while connecting to a malicious wireless network. (bnc#1136424)

CVE-2019-12382: An issue was discovered in drm_load_edid_firmware in
drivers/gpu/drm/drm_edid_load.c in the Linux kernel There was an
unchecked kstrdup of fwstr, which might allow an attacker to cause a
denial of service (NULL pointer dereference and system crash).
(bnc#1136586)

CVE-2019-5489: The mincore() implementation in mm/mincore.c in the
Linux kernel allowed local attackers to observe page cache access
patterns of other processes on the same system, potentially allowing
sniffing of secret information. (Fixing this affects the output of the
fincore program.) Limited remote exploitation may be possible, as
demonstrated by latency differences in accessing public files from an
Apache HTTP Server. (bnc#1120843).

CVE-2019-11833: fs/ext4/extents.c in the Linux kernel did not zero out
the unused memory region in the extent tree block, which might allow
local users to obtain sensitive information by reading uninitialized
data in the filesystem. (bnc#1135281)

CVE-2018-7191: In the tun subsystem in the Linux kernel before
4.13.14, dev_get_valid_name is not called before register_netdevice.
This allowed local users to cause a denial of service (NULL pointer
dereference and panic) via an ioctl(TUNSETIFF) call with a dev name
containing a / character. This is similar to CVE-2013-4343.
(bnc#1135603)

CVE-2019-11190: The Linux kernel allowed local users to bypass ASLR on
setuid programs (such as /bin/su) because install_exec_creds() is
called too late in load_elf_binary() in fs/binfmt_elf.c, and thus the
ptrace_may_access() check has a race condition when reading
/proc/pid/stat. (bnc#1131543)

CVE-2019-11815: An issue was discovered in rds_tcp_kill_sock in
net/rds/tcp.c in the Linux kernel There was a race condition leading
to a use-after-free, related to net namespace cleanup. (bnc#1134537)

CVE-2019-11884: The do_hidp_sock_ioctl function in
net/bluetooth/hidp/sock.c in the Linux kernel allowed a local user to
obtain potentially sensitive information from kernel stack memory via
a HIDPCONNADD command, because a name field may not end with a '\0'
character. (bnc#1134848)

CVE-2018-17972: An issue was discovered in the proc_pid_stack function
in fs/proc/base.c in the Linux kernel It did not ensure that only root
may inspect the kernel stack of an arbitrary task, allowing a local
attacker to exploit racy stack unwinding and leak kernel task stack
contents. (bnc#1110785)

CVE-2019-11486: The Siemens R3964 line discipline driver in
drivers/tty/n_r3964.c in the Linux kernel has multiple race
conditions. (bnc#1133188)

The following new features were implemented: Updated the Chelsio
cxgb4vf driver with the latest upstream patches. (fate#321660)

Backported changes into e1000e kernel module to support systems using
the Intel I219-LM NIC chip. (fate#326719)

Import QLogic/Cavium qedr driver (RDMA) into the kernel. (fate#321747)

Update the QLogic/Cavium qed driver (NET). (fate#321703)

Update the QLogic/Cavium qede driver (NET). (fate#321702)

Update the Chelsio iw_cxgb4 driver with the latest upstream patches.
(fate#321661)

Update the Chelsio cxgb4 driver with the latest upstream patches.
(fate#321658)

Update support for Intel Omni Path (OPA) kernel driver. (fate#321473)

Update the QIB driver to the latest upstream version for up-to-date
functionality and hardware support. (fate#321231)

The update package also includes non-security fixes. See advisory for
details.

  - CVE-2019-3846, CVE-2019-10126
    huangwen reported multiple buffer overflows in the
    Marvell wifi (mwifiex) driver, which a local user could
    use to cause denial of service or the execution of
    arbitrary code.

  - CVE-2019-5489
    Daniel Gruss, Erik Kraft, Trishita Tiwari, Michael
    Schwarz, Ari Trachtenberg, Jason Hennessey, Alex
    Ionescu, and Anders Fogh discovered that local users
    could use the mincore() system call to obtain sensitive
    information from other processes that access the same
    memory-mapped file.

  - CVE-2019-9500, CVE-2019-9503
    Hugues Anguelkov discovered a buffer overflow and
    missing access validation in the Broadcom FullMAC wifi
    driver (brcmfmac), which a attacker on the same wifi
    network could use to cause denial of service or the
    execution of arbitrary code.

  - CVE-2019-11477
    Jonathan Looney reported that a specially crafted
    sequence of TCP selective acknowledgements (SACKs)
    allows a remotely triggerable kernel panic.

  - CVE-2019-11478
    Jonathan Looney reported that a specially crafted
    sequence of TCP selective acknowledgements (SACKs) will
    fragment the TCP retransmission queue, allowing an
    attacker to cause excessive resource usage.

  - CVE-2019-11479
    Jonathan Looney reported that an attacker could force
    the Linux kernel to segment its responses into multiple
    TCP segments, each of which contains only 8 bytes of
    data, drastically increasing the bandwidth required to
    deliver the same amount of data.

  This update introduces a new sysctl value to control the minimal MSS
  (net.ipv4.tcp_min_snd_mss), which by default uses the formerly hard
  coded value of 48. We recommend raising this to 536 unless you know
  that your network requires a lower value.

  - CVE-2019-11486
    Jann Horn of Google reported numerous race conditions in
    the Siemens R3964 line discipline. A local user could
    use these to cause unspecified security impact. This
    module has therefore been disabled.

  - CVE-2019-11599
    Jann Horn of Google reported a race condition in the
    core dump implementation which could lead to a
    use-after-free. A local user could use this to read
    sensitive information, to cause a denial of service
    (memory corruption), or for privilege escalation.

  - CVE-2019-11815
    It was discovered that a use-after-free in the Reliable
    Datagram Sockets protocol could result in denial of
    service and potentially privilege escalation. This
    protocol module (rds) is not auto loaded on Debian
    systems, so this issue only affects systems where it is
    explicitly loaded.

  - CVE-2019-11833
    It was discovered that the ext4 filesystem
    implementation writes uninitialised data from kernel
    memory to new extent blocks. A local user able to write
    to an ext4 filesystem and then read the filesystem
    image, for example using a removable drive, might be
    able to use this to obtain sensitive information.

  - CVE-2019-11884
    It was discovered that the Bluetooth HIDP implementation
    did not ensure that new connection names were
    null-terminated. A local user with CAP_NET_ADMIN
    capability might be able to use this to obtain sensitive
    information from the kernel stack."

    value:
"The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.180 to
receive various security and bugfixes.

The following security bugs were fixed :

CVE-2019-11477: A sequence of SACKs may have been crafted such that
one can trigger an integer overflow, leading to a kernel panic.

CVE-2019-11478: It was possible to send a crafted sequence of SACKs
which will fragment the TCP retransmission queue. An attacker may have
been able to further exploit the fragmented queue to cause an
expensive linked-list walk for subsequent SACKs received for that same
TCP connection.

CVE-2019-11479: An attacker could force the Linux kernel to segment
its responses into multiple TCP segments. This would drastically
increased the bandwidth required to deliver the same amount of data.
Further, it would consume additional resources such as CPU and NIC
processing power.

CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and
possibly escalate privileges was found in the mwifiex kernel module
while connecting to a malicious wireless network. (bnc#1136424)

CVE-2019-12382: An issue was discovered in drm_load_edid_firmware in
drivers/gpu/drm/drm_edid_load.c in the Linux kernel, there was an
unchecked kstrdup of fwstr, which might have allowed an attacker to
cause a denial of service (NULL pointer dereference and system crash).
(bnc#1136586)

CVE-2019-5489: The mincore() implementation in mm/mincore.c in the
Linux kernel allowed local attackers to observe page cache access
patterns of other processes on the same system, potentially allowing
sniffing of secret information. (Fixing this affects the output of the
fincore program.) Limited remote exploitation may have been possible,
as demonstrated by latency differences in accessing public files from
an Apache HTTP Server. (bnc#1120843)

CVE-2019-11833: fs/ext4/extents.c in the Linux kernel did not zero out
the unused memory region in the extent tree block, which might have
allowed local users to obtain sensitive information by reading
uninitialized data in the filesystem. (bnc#1135281)

CVE-2018-7191: In the tun subsystem in the Linux kernel,
dev_get_valid_name was not called before register_netdevice. This
allowed local users to cause a denial of service (NULL pointer
dereference and panic) via an ioctl(TUNSETIFF) call with a dev name
containing a / character. (bnc#1135603)

CVE-2019-11190: The Linux kernel allowed local users to bypass ASLR on
setuid programs (such as /bin/su) because install_exec_creds() was
called too late in load_elf_binary() in fs/binfmt_elf.c, and thus the
ptrace_may_access() check had a race condition when reading
/proc/pid/stat. (bnc#1132472)

CVE-2019-11815: An issue was discovered in rds_tcp_kill_sock in
net/rds/tcp.c in the Linux kernel There was a race condition leading
to a use-after-free, related to net namespace cleanup. (bnc#1134537)

CVE-2019-11884: The do_hidp_sock_ioctl function in
net/bluetooth/hidp/sock.c in the Linux kernel allowed a local user to
obtain potentially sensitive information from kernel stack memory via
a HIDPCONNADD command, because a name field may not end with a '\0'
character. (bnc#1134848)

CVE-2018-17972: An issue was discovered in the proc_pid_stack function
in fs/proc/base.c in the Linux kernel It did not ensure that only root
may inspect the kernel stack of an arbitrary task, allowing a local
attacker to exploit racy stack unwinding and leak kernel task stack
contents. (bnc#1110785)

CVE-2019-11486: The Siemens R3964 line discipline driver in
drivers/tty/n_r3964.c in the Linux kernel had multiple race
conditions. (bnc#1133188)

The update package also includes non-security fixes. See advisory for
