CVE-2026-44662 - rust-openssl vulnerable to heap buffer overflow when encrypting with AES key-wra

CVE-2026-44662

GHSA-xv59-967r-8726 MEDIUM rust/openssl

CVE: CVE-2026-44662

CipherCtxRef::cipher_update, CipherCtxRef::cipher_update_vec, and symm::Crypter::update incorrectly sized output buffers when used with AES key-wrap-with-padding ciphers (EVP_aes_{128,192,256}_wrap_pad). For a non-multiple-of-8 input, OpenSSL writes up to 7 bytes past the end of the caller's buffer or Vec, producing attacker-controllable heap corruption when the plaintext length is attacker-influenced.

This only impacts users using AES key-wrap-with-padding ciphers.
