From: Greg Kroah-Hartman <gregkh@kernel.org>

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

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

remoteproc: qcom: Fix leak when custom dump_segments addition fails

Free allocated minidump_region 'name' in qcom_add_minidump_segments()
when failing before adding the region to 'dump_segments'. Otherwise,
the 'name' is not tracked and is never freed by qcom_minidump_cleanup().

Return error when adding to 'dump_segments' fails.

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:
