CVE-2020-6514

CVE-2020-6514 익스플로잇 익스플로잇을 작성할 때, 원래 WebRTC 소스를 변경하고 다시 컴파일하여 대상 장치로 전송되는 SCTP 패킷을 변경했습니다. 하지만 이 방법은 폐쇄형 소스 애플리케이션을 공격하는 데 실용적이지 않았기 때문에, 결국 Frida를 사용하여 공격 장치의 바이너리를 후킹하는 방식으로 전환했습니다. Frida의 후킹 기능은 특정 네이티브 함수 호출 전후에 코드를 실행할 수 있게 해 주며, 이를 통해 익스플로잇이 발신 SCTP 패킷을 변경하고 수신 패킷을 검사할 수 있었습니다. 기능적으로는 공격...

EUVD-2026-76384

In the Linux kernel, the following vulnerability has been resolved: sctp: drop a chunk if its transport was removed sctprcv resolves the transport once per packet and leaves it in chunk-transport. The lookup reference, or the one sctpaddbacklog takes if the socket is owned by userspace, keeps it...

EUVD-2026-64523

In the Linux kernel, the following vulnerability has been resolved: sctp: clear newtransport when removing a peer sctpprocessasconfparam stores a newly added peer transport in asoc-newtransport. After all parameters in the ASCONF chunk have been processed, sctpsfdoasconf uses this pointer to send...

GHSA-2QJ4-MMR9-4V2F Netty: Memory Exhaustion in SctpMessageCompletionHandler

Summary SctpMessageCompletionHandler does not limit the total size of buffered fragments, allowing an unauthenticated attacker to cause an OutOfMemoryError by sending large SCTP fragments. Details io.netty.handler.codec.sctp.SctpMessageCompletionHandler buffers fragments for incomplete SCTP...

CVE-2025-40281

In the Linux kernel, CVE-2025-40281 affects SCTP in net/sctp/transport.c, where a shift-out-of-bounds could occur in sctp_transport_update_rto if rto_alpha_max/rto_beta_max were very large. The fix adds a run-time test to prevent regressions and includes READ_ONCE() annotations since sysctl value...
