## Description

Vim is an open source, command line text editor. From 9.2.0511 until
9.2.0844, json\_decode\_item() in src/json.c can retain a stale pointer after
json\_decode\_string() invokes channel\_fill() to refill and free the current
buffer, causing the error path to read freed memory instead of
reader->js\_buf + reader->js\_used when an invalid JSON string spans buffers.
This issue is fixed in version 9.2.0844.
