"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.

"An update for kernel-alt is now available for Red Hat Enterprise Linux
7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The kernel-alt packages provide the Linux kernel version 4.x.

Security Fix(es) :

* Kernel: speculative bounds check bypass store (CVE-2018-3693)

* kernel: Use-after-free due to race condition in AF_PACKET
implementation (CVE-2018-18559)

* kernel: Heap overflow in mwifiex_update_bss_desc_with_ie function in
marvell/mwifiex/scan.c (CVE-2019-3846)

* kernel: af_alg_release() in crypto/af_alg.c neglects to set a NULL
value for a certain structure member, which leads to a use-after-free
in sockfs_setattr (CVE-2019-8912)

* kernel: Heap overflow in mwifiex_uap_parse_tail_ies function in
drivers/net /wireless/marvell/mwifiex/ie.c (CVE-2019-10126)

* kernel: Count overflow in FUSE request leading to use-after-free
issues. (CVE-2019-11487)

* kernel: heap overflow in mwifiex_update_vs_ie() function of Marvell
WiFi driver (CVE-2019-14816)

* kernel: buffer overflow in cfg80211_mgd_wext_giwessid in
net/wireless/ wext-sme.c (CVE-2019-17133)

* kernel: heap overflow in mwifiex_set_uap_rates() function of Marvell
Wifi Driver leading to DoS (CVE-2019-14814)

* kernel: heap-overflow in mwifiex_set_wmm_params() function of
Marvell WiFi driver leading to DoS (CVE-2019-14815)

* kernel: (powerpc) incomplete Spectre-RSB mitigation leads to
information exposure (CVE-2019-18660)

For more details about the security issue(s), including the impact, a
CVSS score, acknowledgments, and other related information, refer to
the CVE page(s) listed in the References section.

Bug Fix(es) :

* Kernel panic on job cleanup, related to SyS_getdents64 (BZ#1702057)

* Kernel modules generated incorrectly when system is localized to
non-English language (BZ#1705285)

* RHEL-Alt-7.6 - Fixup tlbie vs store ordering issue on POWER9
(BZ#1756270)"
