CVE-2026-44662

Description

A flaw was found in rust-openssl. When using AES key-wrap-with-padding ciphers (EVP_aes_{128,192,256}_wrap_pad) with an input that is not a multiple of 8, the output buffers are incorrectly sized. This can lead to attacker-controllable heap corruption, allowing an attacker to write up to 7 bytes past the end of the buffer. This vulnerability impacts users where the plaintext length is influenced by an attacker.
