CVE-2026-102716: NetX RTSP server packet pool exhaustion in Session header parsing

CVE-2026-102716 · Severity: info · Published 2026-09-29

A network-accessible RTSP server in NetX can be forced to become unresponsive by an unauthenticated attacker sending malformed requests with invalid Session headers. The server fails to properly release memory buffers when processing these requests, causing the packet pool to be depleted within 26 requests. Once the pool is exhausted, the server stops accepting new connections and may affect other applications sharing the same memory pool.

Technologies: Microsoft NetX. Vendors: Microsoft.

Technical details

An RTSP parser in NetX returns a raw NetX error code instead of an RTSP status code when the Session header cannot be parsed, causing the error handler to take an unrecognized code path that fails to release an already-allocated response packet. The vulnerability allows unauthenticated network clients to trigger this condition repeatedly, exhausting the shared packet pool and causing denial of service to the RTSP server and potentially other components using the same memory allocator.
