CVE-2025-69421Public exploitNetwork attack vector

Application crash via unchecked PKCS#12 content pointer

Published Jan 27, 2026 · Updated Jan 27, 2026

NULL pointer dereference in OpenSSL allows attackers to crash applications that process a malformed PKCS#12 EncryptedData object. The PKCS12_unpack_p7encdata() path passes a NULL oct pointer when encryptedContent is absent, and PKCS12_item_decrypt_d2i_ex() dereferences it without checking. Exploitation requires delivery and processing of the crafted file; the result is an application crash without code execution or memory disclosure.
