CVE ID :CVE-2026-43823
Published : July 23, 2026, 3:17 p.m. | 1 hour, 33 minutes ago
Description :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.
