CVE-2026-22791

A flaw was found in openCryptoki, a library for cryptographic operations. A local attacker can exploit a heap buffer overflow vulnerability within the CKMECDHAESKEYWRAP implementation. By providing a compressed Elliptic Curve EC public key and invoking the CWrapKey function, the attacker can...

CVE-2026-22791 openCryptoki incorrectly calculates the buffer size in C_WrapKey with CKM_ECDH_AES_KEY_WRAP

openCryptoki is a PKCS11 library and tools for Linux and AIX. In 3.25.0 and 3.26.0, there is a heap buffer overflow vulnerability in the CKMECDHAESKEYWRAP implementation allows an attacker with local access to cause out-of-bounds writes in the host process by supplying a compressed EC public key...
