Published on September 29, 2026
A malformed Session header permanently orphans one packet-pool block per RTSP request
In Eclipse ThreadX NetX Duo versions up to and including 6.5.2.202603, the RTSP server returns a raw parser error for a malformed Session header and never releases the response packet it allocated.
