{"cve":"CVE-2020-15204","nvd":{"published":"2020-09-25T19:15:15.713","modified":"2026-06-17T02:56:15.643","status":"Modified","description":"In eager mode, TensorFlow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1 does not set the session state. Hence, calling `tf.raw_ops.GetSessionHandle` or `tf.raw_ops.GetSessionHandleV2` results in a null pointer dereference In linked snippet, in eager mode, `ctx->session_state()` returns `nullptr`. Since code immediately dereferences this, we get a segmentation fault.
