CVE-2026-14164 is a double-free vulnerability in libarchive's RAR5 reader involving a dangling filtered_buf pointer in init_unpack(). When a specially crafted RAR5 archive triggers unpacking-state reinitialization, the buffer may be freed without clearing its pointer. Processing a subsequent archive entry can then free the same memory region again, potentially terminating applications using the vulnerable libarchive API and causing denial of service.
