[LSN-0054-1] Linux kernel vulnerability

---------- Forwarded message ---------
From:
Date: Aug 29, 2019 4:35AM

It was discovered that the USB video device class implementation in the
Linux kernel did not properly validate control bits, resulting in an out of
bounds buffer read. A local attacker could use this to possibly expose
sensitive information (kernel memory). (CVE-2019-2101)

It was discovered that the Marvell Wireless LAN device driver in the Linux
kernel did not properly validate the BSS descriptor. A local attacker could
possibly use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2019-3846)

It was discovered that a heap buffer overflow existed in the Marvell
Wireless LAN device driver for the Linux kernel. An attacker could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2019-10126)

It was discovered that the PowerPC dlpar implementation in the Linux kernel
did not properly check for allocation errors in some situations. A local
attacker could possibly use this to cause a denial of service (system
crash). (CVE-2019-12614)

It was discovered that a NULL pointer dereference vulnerabilty existed in
the Near-field communication (NFC) implementation in the Linux kernel. An
attacker could use this to cause a denial of service (system crash).
(CVE-2019-12818)

It was discovered that the MDIO bus devices subsystem in the Linux kernel
improperly dropped a device reference in an error condition, leading to a
use-after-free. An attacker could use this to cause a denial of service
(system crash). (CVE-2019-12819)

It was discovered that a NULL pointer dereference vulnerability existed in
the Near-field communication (NFC) implementation in the Linux kernel. A
local attacker could use this to cause a denial of service (system crash).
(CVE-2019-12984)

Jann Horn discovered that the ptrace implementation in the Linux kernel did
not properly record credentials in some situations. A local attacker could
use this to cause a denial of service (system crash) or possibly gain
administrative privileges. (CVE-2019-13272)
