# CVE-2026-29508: ReadyMedia 1.3.0 - 1.3.3 Stack Buffer Overflow via DFF Parser

- Exploited (CISA KEV): no
- Published: 2026-11-02
- CVSS: 8.7 HIGH (v4.0)
- EPSS: no score
- CWE: CWE-121

ReadyMedia (formerly MiniDLNA) versions 1.3.0 through 1.3.3 contain a stack-based buffer overflow vulnerability that allows remote attackers to corrupt stack memory by crafting a malicious DFF audio file with an oversized PROP chunk size value that is used unvalidated to allocate a variable-length stack array and read file data into it. Attackers can place a crafted DFF file in a directory monitored by ReadyMedia to trigger automatic parsing via inotify, achieving remote code execution on unprotected builds or denial of service on hardened builds with stack protections.

"No public claim" means no vendor statement names this CVE; "Before feed history" means the CVE is older than the vendor feed. In both cases generic rules may still block it.
