# CVE-2026-14164: Libarchive: double-free vulnerability in rar5 decompression logic via dangling filtered_buf pointer in init_unpack()

Status: published. Published: 2026-06-30. Updated: 2026-11-05.

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.

## Remediation

- workaround: No mitigation is currently available that meets Red Hat Product Security's standards for usability, deployment, applicability, or stability. Customers are advised to apply the appropriate security update once it becomes available. (source: CNA: redhat)
