DESCRIPTION

* CVE-2017-5986: Denial-of-service when using SCTP socket with concurrent thread.

A BUG_ON() could be triggered when queueing data in a full SCTP socket
while another thread disassociates the first thread from the socket. A
local attacker could use this flaw to cause a denial-of-service.


* CVE-2017-6353: Denial-of-service when peeling off a sctp socket.

A logic error when peeling off a sctp socket could lead to a double free
or a deadlock. A local user could use this flaw to cause a
denial-of-service.


* Use after free in 8250 PCI serial driver.

The generic 8250 serial driver for PCI devices does not correctly resuming a
device which can trigger a use after free condition and kernel panic.


* Memory corruption in HyperV SCSI driver.

A logic error when allocating memory for HyperV SCSI commands can trigger
memory corruption and a kernel panic.


* Denial of service in HyperV virtual network initialization.

A race condition between registering a network device and sending packets when
initializing a HyperV virtual network device can trigger memory corruption and
a kernel panic.


* Denial of service when reopening TTY device.

A race condition when reopening a TTY device and initializing a line discipline
can trigger memory corruption and a kernel panic.


* Denial of service in ext4 extended attribute checksums.

A race condition in the ext4 filesystem driver can cause incorrect checksums to
be calculated for extended attributes which can allow a local user to cause a
denial of service.
