Kerentanan Incorrect Calculation pada libssh, redhat openshift container platform +1 lainnya. Skor CVSS 3.1 8.8 (High) menurut NVD.

Deskripsi (NVD)

A flaw was found in libssh versions built with OpenSSL versions older than 3.0, specifically in the ssh_kdf() function responsible for key derivation. Due to inconsistent interpretation of return values where OpenSSL uses 0 to indicate failure and libssh uses 0 for success—the 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.
