DESCRIPTION

* CVE-2018-10323: NULL pointer dereference when converting extents-format to B+tree in XFS filesystem.

A logic error when converting extents-format to B+tree in XFS filesystem
could lead to a NULL pointer dereference. A local attacker could use
this flaw with a crafted XFS image to cause a denial-of-service.


* Use-after-free when creating a ANSI/IEEE 802.2 LLC type 2 socket.

A logic error when creating a ANSI/IEEE 802.2 LLC type 2 socket could
lead to a use-after-free. A local attacker could use this flaw to cause
a denial-of-service.


* Use-after-free in perf subsystem when iterating children siblings.

A race condition in perf subsystem when iterating children siblings
could lead to a use-after-free. A local attacker could use this flaw to
cause a denial-of-service.


* Denial-of-service in ADDI-DATA APCI_1500 COMEDI driver.

A missing check on user input when using ADDI-DATA APCI_1500 COMEDI
driver could lead to an out-of-bounds access. A local attacker could use
this flaw to cause a denial-of-service.


* Use-after-free when setting TCP_CONGESTION tcp socket option.

A logic error when setting TCP_CONGESTION tcp socket option and later on
freeing it could lead to a use-after-free. A local attacker could use this
flaw to cause a denial-of-service.


* Denial-of-service in the ALSA info subsystem.

A too verbose debug print could be triggered from user space in the ALSA
info subsystem. A local attacker could use this flaw to cause a denial-
of-service.


* Denial-of-service in Prism2.5/3 USB driver.

A missing check on endpoint type of a plugged USB device could lead to
an invalid memory access. A local attacker could use this flaw and a
malicious USB device to cause a denial-of-service.


* Information leak in the AdLib FM cards driver.

A missing zeroing of on stack data in the AdLib FM cards driver could
lead to an information leak. A local attacker could use this flaw to
leak information about running kernel and facilitate an attack.


* NULL pointer dereference when receiving packet over a tunnel device.

A logic error when receiving packet over a tunnel device could lead to a
NULL pointer dereference. A remote attacker could use this flaw to cause
a denial-of-service.


* Out-of-bounds access in USB Infinity USB Unlimited Phoenix driver.

A missing check on user input when using USB Infinity USB Unlimited
Phoenix driver could lead to an out-of-bounds access. A local attacker
could use this flaw to cause a denial-of-service.


* Out-of-bounds access when using Amateur Radio AX.25 Level 2 protocol socket.

Logic errors when connecting or sending messages over Amateur Radio
AX.25 Level 2 protocol socket could lead to out-of-bounds accesses. A
local attacker could use this flaw to cause a denial-of-service.
