CVE-2025-5372
Good to know:
Date: July 4, 2025
In libssh before 0.11.2 ssh_kdf() returns a success code on certain failures for libssh built with OpenSSL < 3.0. This is caused by the alias of OpenSSL return value 0 (failure) with libssh SSH_OK (0). Returning success code from the ssh_kdf() function without initializing the output buffers can lead to use of uninitialized cryptographic keys and failing to encrypt/decrypt following communication.
