  "message": "Fix function pointer type mismatch when freeing ECX keys\n\nossl_ecx_key_free is declared as void(ECX_KEY *) but registered\ndirectly in the X25519/X448/Ed25519/Ed448 keymgmt OSSL_DISPATCH\ntables for OSSL_FUNC_KEYMGMT_FREE, which is invoked through a\nvoid(*)(void *) pointer in evp_keymgmt_freedata. Calling a function\nthrough a pointer to an incompatible function type is undefined\nbehavior and is reported by UndefinedBehaviorSanitizer on every\nECX key free:\n\n    crypto/evp/keymgmt_meth.c:392:5: runtime error: call to function\n      ossl_ecx_key_free through pointer to incorrect function type\n      \u0027void (*)(void *)\u0027\n    crypto/ec/ecx_key.c:65: note: ossl_ecx_key_free defined here\n\nAll four algorithms share the same MAKE_KEYMGMT_FUNCTIONS dispatch\nmacro, so they hit the same UB; UBSan just deduplicates the report\non the first call.\n\nMirror the wrapper pattern used by ml_kem_free_key, ml_dsa_free_key,\nslh_dsa_free_key, dsa_freedata, ec_freedata, and lms_free_key: add\na small static ecx_free_key with the correct OSSL_FUNC_keymgmt_free_fn\nsignature that forwards to ossl_ecx_key_free, and register the\nwrapper in the dispatch macro. The existing direct callers of\nossl_ecx_key_free in ecx_kmgmt.c are unchanged since they pass a\ntyped ECX_KEY *.\n\nCLA: trivial\n\nReviewed-by: Nikola Pajkovsky \u003cnikolap@openssl.org\u003e\nReviewed-by: Paul Yang \u003cpaulyang.inf@gmail.com\u003e\nReviewed-by: Tomas Mraz \u003ctomas@openssl.foundation\u003e\nMergeDate: Thu May 14 09:31:58 2026\n(Merged from https://github.com/openssl/openssl/pull/31078)\n",
