swift-crypto: swift-crypto: Denial of Service due to double-free during RSA public key initialization

A flaw was found in swift-crypto. When an RSA Rivest-Shamir-Adleman public key is initialized from DER Distinguished Encoding Rules or PEM Privacy-Enhanced Mail formatted bytes, and an error occurs during the decoding process, a double-free vulnerability can be triggered. This issue, occurring wh...

CVE-2026-43823

When initializing an RSA public key from DER or PEM bytes throws an error, the EVPPKEY is double-freed: first in the catch block, then in the deinit. This can lead to a crash on future memory allocations. This double-free manifests when BoringSSL cannot decode the public key from the bytes...

CVE-2026-43823

A double-free vulnerability exists in swift-crypto (specifically within the swiftlang package) when initializing an RSA public key from DER or PEM formatted bytes. If BoringSSL fails to decode the provided bytes, the EVP_PKEY* is freed twice—once in the catch block and again during deinitializati...
