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...
