1) Unchecked Return Value (CVE-ID: CVE-2026-31790)

CWE-ID: CWE-252 - Unchecked Return Value

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to incorrect failure handling in RSA KEM RSASVE encapsulation when processing an attacker-supplied invalid RSA public key with EVP_PKEY_encapsulate(). A remote attacker can supply an invalid RSA public key to disclose sensitive information.

The issue affects applications using RSA/RSASVE encapsulation without validating the supplied public key first.
