CVE-2026-45784
Published:May 20, 2026
Updated:May 20, 2026
"CipherCtxRef::cipher_update_inplace" 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. This method was missed in the fix for GHSA-xv59-967r-8726
