Summary
It was discovered that the Atheros 802.11ac wireless USB device driver in
the Linux kernel did not properly validate device metadata. A physically
proximate attacker could use this to cause a denial of service (system
crash). (CVE-2019-15099)
It was discovered that a race condition existed in the Virtual Video Test
Driver in the Linux kernel. An attacker with write access to /dev/video0 on
a system with the vivid module loaded could possibly use this to gain
administrative privileges. (CVE-2019-18683)
It was discovered that the btrfs file system in the Linux kernel did not
properly validate metadata, leading to a NULL pointer dereference. An
attacker could use this to specially craft a file system image that, when
mounted, could cause a denial of service (system crash). (CVE-2019-18885)
It was discovered that the crypto subsystem in the Linux kernel did not
properly deallocate memory in certain error conditions. A local attacker
could use this to cause a denial of service (kernel memory exhaustion).
(CVE-2019-19050, CVE-2019-19062)
It was discovered that the RSI 91x WLAN device driver in the Linux kernel
did not properly deallocate memory in certain error conditions. A local
attacker could use this to cause a denial of service (kernel memory
exhaustion). (CVE-2019-19071)
It was discovered that the Broadcom Netxtreme HCA device driver in the
Linux kernel did not properly deallocate memory in certain error
conditions. A local attacker could possibly use this to cause a denial of
service (kernel memory exhaustion). (CVE-2019-19077)
It was discovered that the Atheros 802.11ac wireless USB device driver in
the Linux kernel did not properly deallocate memory in certain error
conditions. A local attacker could possibly use this to cause a denial of
service (kernel memory exhaustion). (CVE-2019-19078)
It was discovered that the Qualcomm IPC Router TUN device driver in the
Linux kernel did not properly deallocate memory in certain situations. A
local attacker could possibly use this to cause a denial of service (kernel
memory exhaustion). (CVE-2019-19079)
It was discovered that the AMD GPU device drivers in the Linux kernel did
not properly deallocate memory in certain error conditions. A local
attacker could use this to possibly cause a denial of service (kernel
memory exhaustion). (CVE-2019-19082)
Dan Carpenter discovered that the AppleTalk networking subsystem of the
Linux kernel did not properly handle certain error conditions, leading to a
NULL pointer dereference. A local attacker could use this to cause a denial
of service (system crash). (CVE-2019-19227)
Or Cohen discovered that the virtual console subsystem in the Linux kernel
did not properly restrict writes to unimplemented vcsu (unicode) devices. A
local attacker could possibly use this to cause a denial of service (system
crash) or have other unspecified impacts. (CVE-2019-19252)
It was discovered that the KVM hypervisor implementation in the Linux
kernel did not properly handle ioctl requests to get emulated CPUID
features. An attacker with access to /dev/kvm could use this to cause a
denial of service (system crash). (CVE-2019-19332)
It was discovered that the ext4 file system implementation in the Linux
kernel did not properly handle certain conditions. An attacker could use
this to specially craft an ext4 file system that, when mounted, could cause
a denial of service (system crash) or possibly execute arbitrary code.
(CVE-2019-19767)
It was discovered that the B2C2 FlexCop USB device driver in the Linux
kernel did not properly validate device metadata. A physically proximate
attacker could use this to cause a denial of service (system crash).
(CVE-2019-15291)
