CVE-2026-102760

When NetX Secure is built with NX_SECURE_KEY_CLEAR, a vulnerability exists where TLS records are wiped after being handed to the TCP layer . Because the TCP layer may have already released the packet chain back to the packet pool , the wipe operation writes zeros into packets that are free or in ...

CVE-2026-102760

When NetX Secure is built with NXSECUREKEYCLEAR, every TLS record sent on an active session is wiped after it has been handed to TCP. By then the TCP layer owns the packet chain and may already have released it to the packet pool. The wipe therefore writes zeros into packets that are free or in u...
