CentSDR commit e40795 was discovered to contain a stack overflow in the "Thread1" function.
AnalysisAI
CentSDR's Thread1 function suffers a remote stack overflow, leading to denial of service without authentication. A public proof-of-concept is available, but no active exploitation has been observed. The low EPSS score and niche user base suggest limited real-world risk despite the high CVSS score.
Technical ContextAI
CentSDR is an open‑source software‑defined radio (SDR) application that likely processes network‑received I/Q samples. The vulnerability resides in the 'Thread1' function, where a stack‑based buffer overflow (CWE-121) can be triggered by attacker‑supplied data. A fixed‑size local buffer on the stack is overwritten, corrupting adjacent memory and causing the application to crash. The CPE string is generic ('n/a'), but the product is confirmed by the repository reference.
RemediationAI
No official patch is available; the GitHub issue remains open. As a temporary workaround, restrict network access to the CentSDR service using firewall rules to allow only trusted IP addresses. If the affected Thread1 processing can be disabled without breaking required functionality, do so. Monitor the GitHub issue for a fix and apply it as soon as it is published.
