+  "details": "### Summary\n``aes::unwrap_key()`` has an incorrect bounds assertion on the out buffer size, which can lead to out-of-bounds write.\n\n### Details\n``aes::unwrap_key()`` contains an incorrect assertion: it checks that `out.len() + 8 <= in_.len()`, but this condition is reversed. The intended invariant is `out.len() >= in_.len() - 8`, ensuring the output buffer is large enough.\n\nBecause of the inverted check, the function only accepts buffers at or below the minimum required size and rejects larger ones. If a smaller buffer is provided the function will write past the end of `out` by `in_.len() - 8 - out.len()` bytes, causing an out-of-bounds write from a safe public function.\n\n### Impact\nVulnerable applications using AES keywrap and allowing attacker controlled buffer sizes could have an attacker trigger an out-of-bounds write.",
