  script_tag(name:"insight", value:"This kernel-linus update is based on the upstream 5.3.11 and fixes at least
the following security issues:

Insufficient access control in a subsystem for Intel (R) processor graphics
may allow an authenticated user to potentially enable escalation of
privilege via local access (CVE-2019-0155).

A Spectre SWAPGS gadget was found in the Linux kernel's implementation of
system interrupts. An attacker with local access could use this information
to reveal private data through a Spectre like side channel (CVE-2019-1125).

A flaw was found in the Linux kernel's Bluetooth implementation of UART.
An attacker with local access and write permissions to the Bluetooth
hardware could use this flaw to issue a specially crafted ioctl function
call and cause the system to crash (CVE-2019-10207).

TSX Asynchronous Abort condition on some CPUs utilizing speculative
execution may allow an authenticated user to potentially enable
information disclosure via a side channel with local access
(CVE-2019-11135).

Improper invalidation for page table updates by a virtual guest operating
system for multiple Intel(R) Processors may allow an authenticated user to
potentially enable denial of service of the host system via local access
(CVE-2018-12207).

For proper mitigations and fixes for these issues, a microcode update is
also needed, either with a bios/uefi update from your hardware vendor or
by installing the microcode-0.20191112-1.mga7.nonfree update (mga#25688).

There is heap-based buffer overflow in the marvell wifi chip driver that
allows local users to cause a denial of service(system crash) or possibly
execute arbitrary code (CVE-2019-14814, CVE-2019-14815, CVE-2019-14816).

An out-of-bounds access issue was found in the way Linux kernel's KVM
hypervisor implements the Coalesced MMIO write operation. It operates on
an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write
indices 'ring->first' and 'ring->last' value could be supplied by a host
user-space process. An unprivileged host user or process with access to
'/dev/kvm' device could use this flaw to crash the host kernel, resulting
in a denial of service or potentially escalating privileges on the system
(CVE-2019-14821).

A buffer overflow flaw was found in the way Linux kernel's vhost
functionality that translates virtqueue buffers to IOVs, logged the buffer
descriptors during migration. A privileged guest user able to pass
descriptors with invalid length to the host when migration is underway,
could use this flaw to increase their privileges on the host
(CVE-2019-14835).

In the Linux kernel before 5.2.14, rds6_inc_info_copy in net/rds/recv.c
allows attackers to obtain sensitive information from kernel stack memory
because tos and flags fields are not initialized (CVE-2019-16714)

rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux
kernel through 5.3.6 lacks a certain upper-bound check, leading ... [Please see the references for more information on the vulnerabilities]");
