Apple Inc. · published 2026-07-23
Source record Collected from the National Vulnerability Database (NVD)
Description
Description by Apple Inc. via the CVE Program.
When initializing an RSA public key from DER or PEM bytes throws an error, the EVP_PKEY* 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 provided. This vulnerability is addressed in swift-crypto version 4.5.1.
