"Wen Huang discovered that the Marvell Wi-Fi device driver in the Linux
kernel did not properly perform bounds checking, leading to a heap
overflow. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2019-14814,
CVE-2019-14815, CVE-2019-14816)

Matt Delco discovered that the KVM hypervisor implementation in the
Linux kernel did not properly perform bounds checking when handling
coalesced MMIO write operations. A local attacker with write access to
/dev/kvm could use this to cause a denial of service (system crash).
(CVE-2019-14821)

Hui Peng and Mathias Payer discovered that the 91x Wi-Fi driver in the
Linux kernel did not properly handle error conditions on
initialization, leading to a double-free vulnerability. A physically
proximate attacker could use this to cause a denial of service (system
crash). (CVE-2019-15504)

It was discovered that the Technisat DVB-S/S2 USB device driver in the
Linux kernel contained a buffer overread. A physically proximate
attacker could use this to cause a denial of service (system crash) or
possibly expose sensitive information. (CVE-2019-15505)

Brad Spengler discovered that a Spectre mitigation was improperly
implemented in the ptrace susbsystem of the Linux kernel. A local
attacker could possibly use this to expose sensitive information.
(CVE-2019-15902)

It was discovered that the IPv6 RDS implementation in the Linux kernel
did not properly initialize fields in a data structure returned to
user space. A local attacker could use this to expose sensitive
information (kernel memory). Please note that the RDS protocol is
blacklisted in Ubuntu by default. (CVE-2019-16714)

It was discovered that an integer overflow existed in the Binder
implementation of the Linux kernel, leading to a buffer overflow. A
local attacker could use this to escalate privileges. (CVE-2019-2181).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."

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)"
