Subject: [PATCH] Fix off-by-one error in udevListInterfacesByStatus
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ever since this function was introduced in 2012 it could've tried
filling in an extra interface name.  That was made worse in 2019 when
the caller functions started accepting NULL arrays of size 0.

This is assigned CVE-2024-1441.
