[PATCH 0/1] [SRU Xenial] CVE-2019-16231

[Tim Gardner]

[Impact]
Unchecked allocation failures in the fjes network driver could cause NULL pointer
access. It was discovered that the Fujitsu ES network device driver for the Linux
kernel did not properly check for errors in some situations, leading to a NULL
pointer dereference. A local attacker could use this to cause a denial of service.

[Test Case]
Given the nature of the failure, no test case is possible.

[Potential regression]
The patch is straightforward. Even if one of the allocation failure paths has an
error, the code is no more broken then it is now. Currently any allocation failure will
cause a seg fault. This patch has been released in Bionic 4.15.0-74.84.
