AI-analyzed exploit summary This repository contains an auto-generated stub module for CVE-2026-14164, a double free vulnerability in libarchive's RAR5 reader. The code includes metadata and a placeholder `run()` method with no functional exploit implementation, only references to external sources for actual PoC details.

Description

A double free issue has been identified in libarchive's RAR5 reader. During parsing of a specially crafted RAR5 archive, the filtered_buf pointer may remain stale after being freed during unpacking state reinitialization. Subsequent processing of another archive entry can trigger a second free of the same memory region, resulting in a double-free condition. Successful exploitation may cause applications using the vulnerable libarchive API to terminate unexpectedly, leading to a denial of service.
