Due to inconsistent interpretation of return values where OpenSSL uses 0 to indicate failure and libssh uses 0 for success\u2014the function may mistakenly return a success status even when key derivation fails. This results in uninitialized cryptographic key buffers being used in subsequent communication, potentially compromising SSH sessions' confidentiality, integrity, and availability."}], "lastModified": "2025-07-04T06:15:24.930", "sourceIdentifier": "secalert@redhat.com"}
