3.7 CVE-2025-46712
Erlang/OTP is a set of libraries for the Erlang programming language. In versions prior to OTP-27.3.4 (for OTP-27), OTP-26.2.5.12 (for OTP-26), and OTP-25.3.2.21 (for OTP-25), Erlang/OTP SSH fails to enforce strict KEX handshake hardening measures by allowing optional messages to be exchanged. This allows a Man-in-the-Middle attacker to inject these messages in a connection during the handshake. This issue has been patched in versions OTP-27.3.4 (for OTP-27), OTP-26.2.5.12 (for OTP-26), and OTP-25.3.2.21 (for OTP-25).

CWE-440 : Expected Behavior Violation
A feature, API, or function does not perform according to its specification. Program uses large timeouts on unconfirmed connections resulting from inconsistency in linked lists implementations. "strncpy" in Linux kernel acts different than libc on x86, leading to expected behavior difference - sort of a multiple interpretation error? Buffer overflow in product stems the use of a third party library function that is expected to have internal protection against overflows, but doesn't.
