Attackers can exploit the underflow in the expression computing blocksize minus aadlen minus authentication tag length to trigger an out-of-bounds read and a memcpy call with a near-SIZE_MAX length argument, causing immediate process crash before any authentication occurs.",

          "details": "- Exploitation is limited to libssh2 clients built with the OpenSSL backend and only occurs when a client initiates an outbound SSH connection to an attacker‑controlled server that negotiates AES‑GCM; unsolicited inbound traffic to your hosts cannot trigger it.  \n- The documented effect is a pre‑authentication crash of the client process (availability only) with no confidentiality or integrity impact.  \n- Because it requires a specific crypto backend and cipher negotiation plus deliberate client interaction with an untrusted server, the practical risk in centrally managed enterprise VM/server environments is low and this CVE can be deprioritized.",
