CVE-2025-56234

CVE-2025-56234 affects Nanda Automation Technology’s AT NA2000 PLC. The root cause is improper handling of TCP RST packets, accepting a broad range of sequence numbers within the receive window rather than requiring an exact match (RFC 5961). This enables an attacker to send numerous random TCP R...

kernel: net: tls: avoid hanging tasks on the tx_lock

A denial-of-service flaw was found in the Linux kernel's TLS implementation. An adversarial network receiver can keep the TCP receive window RWIN at zero for extended periods, causing a thread holding the txlock to sleep indefinitely. Other tasks waiting for this lock become hung, leading to syst...
