WebKit Nightly Build Unspecified Unspecified RESOLVED FIXED InRadar P2 Normal --- 1 ddkilzer ddkilzer webkit-bug-importer oldest_to_newest 2200807 0 ddkilzer 2026-04-15 13:48:36 -0700 Several Security framework APIs (`SecTrustSerialize`, `SecTrustDeserialize`, `SecTrustCopyPropertyListRepresentation`, `SecTrustCreateFromPropertyListRepresentation`, `SecKeyCreateRandomKey`, `SecKeyCreateWithData`) return +1 retained `CFErrorRef` objects through their out parameters, but the APIs are missing the `CF_RETURNS_RETAINED` annotation on those parameters (rdar://161546781). Newer functions in the same headers (`SecTrustCopyTrustStoreContentDigest`, `SecTrustGetAssetVersionNumber`, etc.) already have the annotation, but these older APIs have not been updated. WebKit callers store the raw `CFErrorRef` in a local variable, check it for errors, but never release it -- leaking the error object on every error path. This affects both production code (`CoreIPCSecTrust.mm`, `WKRemoteObjectCoder.mm`, `VirtualAuthenticatorUtils.mm`) and test code (`IPCSerialization.mm`, `Challenge.mm`, `WebTransport.mm`, `_WKWebAuthenticationPanel.mm`, `TestControllerCocoa.mm`). 2200808 1 webkit-bug-importer 2026-04-15 13:52:08 -0700 <rdar://problem/174864243> 2200864 2 ddkilzer 2026-04-15 16:46:39 -0700 Pull request: https://github.com/WebKit/WebKit/pull/62860 2201521 3 ews-feeder 2026-04-17 08:35:25 -0700 Committed 311454@main (12b5e059d376): <https://commits.webkit.org/311454@main> Reviewed commits have been landed.
