    "summary": "wolfCrypt leaks cryptographic information via timing side channel\nwolfSSL and wolfCrypt 4.0.0 and earlier (when configured without `--enable-fpecc`, `--enable-sp`, or` --enable-sp-math`) contain a timing side channel in ECDSA signature generation. This allows a local attacker, able to precisely measure the duration of signature operations, to infer information about the nonces used and potentially mount a lattice attack to recover the private key used. The issue occurs because ecc.c scalar multiplication might leak the bit length.",
