DESCRIPTION

* CVE-2017-11600: Out-of-bound access in network Transformation user configuration interface.

A missing check on user-controlled input in network Transformation user
configuration interface could lead to an out-of-bounds access. A local
attacker could use this flaw to cause a denial-of-service.

Orabug: 28264121


* CVE-2017-7616: Information leak when setting memory policy.

A missing check when setting memory policy through set_mempolicy()
syscall could lead to a stack data leak. A local attacker could use this
flaw to leak information about running kernel and facilitate an attack.

Orabug: 28242478


* CVE-2018-5803: Denial-of-service when receiving forged packet over SCTP socket.

A missing check when receiving a forged packet with custom properties
over SCTP socket could lead to a kernel assert. A remote attacker could
use this flaw to cause a denial-of-service.

Orabug: 28240075


* CVE-2018-1130: Denial-of-service in DCCP message send.

A logic error in the dccp code could lead to a NULL pointer dereference
when transmitting messages, leading to a kernel panic.  An attacker could
use this to cause a denial-of-service.

* CVE-2018-10124: Denial-of-service when using kill() syscall with a too big pid.

A missing check on user input when using kill() syscall with a pid
number higher than integer limit could lead to an overflow. A local
attacker could use this flaw to cause a denial-of-service.

Orabug: 28082931


* CVE-2018-10087: Denial-of-service when using wait() syscall with a too big pid.

A missing check on user input when using wait() syscall with a pid
number higher than integer limit could lead to an overflow. A local
attacker could use this flaw to cause a denial-of-service.

Orabug: 27875488


* CVE-2018-8781: Integer overflow when mapping memory in USB Display Link video driver.

A missing check on user input when mapping memory in USB Display Link
video driver could lead to an integer overflow. A local attacker could
use this flaw to cause a denial-of-service.

Orabug: 27986407


* CVE-2017-18203: Denial-of-service during device mapper destruction.

A race condition between creation and destruction of device mapper
objects can result in an assertion failure, leading to a kernel crash. A
local user could use this flaw to cause a denial-of-service.
