Description
===========

In the Linux kernel, the following vulnerability has been resolved:

scsi: lpfc: Avoid potential ndlp use-after-free in dev_loss_tmo_callbk

Smatch detected a potential use-after-free of an ndlp oject in

Mitigation
==========

The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes.  Individual
changes are never tested alone, but rather are part of a larger kernel
release.  Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all.  If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
	https://git.kernel.org/stable/c/4f09940b5581e44069eb31a66cf7f05c3c35ed04
