[Xenial][SRU][CVE-2017-18232][PATCH 0/1] SAS DoS

[Connor Kuehl]

https://people.canonical.com/~ubuntu-security/cve/2017/CVE-2017-18232.html

>From the link above:

	"The Serial Attached SCSI (SAS) implementation in the Linux kernel through
	4.15.9 mishandles a mutex within libsas, which allows local users to cause
	a denial of service (deadlock) by triggering certain error-handling
	code."

Context adjustment was required for one of the hunks (see the patch for
more information).

Booted and modprobed libsas.
