Vim 9.2.0511 < 9.2.0844 Use-After-Free (GHSA-69ch-22ch-r887)

low Nessus Plugin ID 335162

Synopsis

A text editor installed on the remote host is affected by a use-after-free vulnerability.

Description

The version of Vim installed on the remote host is between 9.2.0511 and 9.2.0844 (exclusive). It is, therefore, affected by a vulnerability as referenced in the GHSA-69ch-22ch-r887 advisory.

 - 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.
 (CVE-2026-73071)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Vim version 9.2.0844 or later.
