NULL Pointer Dereference in OpenSSL PKCS12_item_decrypt_d2i_ex()
CVE-2025-69421 is a NULL pointer dereference in OpenSSL's PKCS#12 processing. When a malformed PKCS#12 file is processed, the PKCS12_item_decrypt_d2i_ex() function dereferences the oct parameter without first verifying that it is non-NULL. The vulnerable condition can be reached when PKCS12_item_decrypt_d2i_ex() is called from PKCS12_unpack_p7encdata() while handling malformed PKCS#12 content. Successful triggering causes the application using OpenSSL to crash. The issue is described as limited to denial of service and not leading to code execution or memory disclosure. Affected branches include OpenSSL 3.6, 3.5, 3.4, 3.3, 3.0, 1.1.1, and 1.0.2.
