+Subject: [PATCH] x509: Avoid NULL-pointer dereference if issuerName is missing
+ in attribute certificate
+
+If neither authoritiyKeyIdentifier nor issuerName are encoded in an
+attribute certificate, the validation in `acert_validator.c:verify()`
+will cause a NULL-pointer dereference via `issued_by()` (the lookup
+with NULL identity will enumerate all trusted certificates).
+
+Fixes: 26930a8c3e42 ("certificate factory can load certs from file")
+Fixes: CVE-2026-78130
+
+CVE: CVE-2026-78130
+Upstream-Status: Backport [https://github.com/strongiswan/strongswan/commit/bee6ce27761e1f38958be36ebe6688ef963c3d22]
