CVE-2026-30364Public exploitNetwork attack vector

Receiver crash via undersized Thread1 stack

Published Apr 15, 2026 · Updated Apr 15, 2026

Stack-based buffer overflow in CentSDR commit e407956 allows remote attackers to crash the receiver through unspecified network input. Thread1 receives a fixed 128-byte working area although its worst-case call chain consumes about 224 bytes under certain builds. Exploitation requires a configuration that produces the oversized call chain; public material does not identify the triggering network input.
