[CVE artful/linux trusty/linux] CVE-2018-7757 -- Memory leak in the SAS subsystem

[Andy Whitcroft]

CVE-2018-7757:
    It was discovered that a memory leak existed in the SAS driver
    subsystem of the Linux kernel. A local attacker could use this to
    cause a denial of service (memory exhaustion).

This fix has arrived by direct application in bionic and stable in other
series.  This remains open in artful and trusty.  Following this email
is a patch for both of these.

Proposing for SRU to artful and trusty.
