| CVE-2026-40253 | openCryptoki is a PKCS#11 library and provides tooling for Linux and AIX. In versions 3.26.0 and below, the BER/DER decoding functions in the shared common library (asn1.c) accept a raw pointer but no buffer length parameter, and trust attacker-controlled BER length fields without validating them against actual buffer boundaries. All primitive decoders are affected: ber_decode_INTEGER, ber_decode_SEQUENCE, ber_decode_OCTET_STRING, ber_decode_BIT_STRING, and ber_decode_CHOICE.

| CVE-2026-23893 | openCryptoki is a PKCS#11 library and provides tooling for Linux and AIX. Versions 2.3.2 and above are vulnerable to symlink-following when running in privileged contexts. A token-group user can redirect file operations to arbitrary filesystem targets by planting symlinks in group-writable token directories, resulting in privilege escalation or data exposure. Token and lock directories are 0770 (group-writable for token users), so any token-group member can plant files and symlinks inside them. | [email protected] | 6.8 | 0.01% | 2026-01-22 | 2026-03-06 |
| CVE-2026-22791 | openCryptoki is a PKCS#11 library and tools for Linux and AIX. In 3.25.0 and 3.26.0, there is a heap buffer overflow vulnerability in the CKM_ECDH_AES_KEY_WRAP implementation allows an attacker with local access to cause out-of-bounds writes in the host process by supplying a compressed EC public key and invoking C_WrapKey. This can lead to heap corruption, or denial-of-service. | [email protected] | 6.6 | 0.01% | 2026-01-13 | 2026-02-03 |
| CVE-2024-0914 | A timing side-channel vulnerability has been discovered in the opencryptoki package while processing RSA PKCS#1 v1.5 padded ciphertexts. This flaw could potentially enable unauthorized RSA ciphertext decryption or signing, even without access to the corresponding private key. | [email protected] | 5.9 | 0.42% | 2024-01-31 | 2026-03-24 |
| CVE-2021-3798 | A flaw was found in openCryptoki. The openCryptoki Soft token does not check if an EC key is valid when an EC key is created via C_CreateObject, nor when C_DeriveKey is used with ECDH public data. This may allow a malicious user to extract the private key by performing an invalid curve attack. | [email protected] | 5.5 | 0.15% | 2022-08-23 | 2024-11-21 |
| CVE-2012-4455 | openCryptoki 2.4.1 allows local users to create or set world-writable permissions on arbitrary files via a symlink attack on the (1) LCK..opencryptoki or (2) LCK..opencryptoki_stdll file in /var/lock/. | [email protected] | 6.2 | 0.04% | 2012-10-10 | 2026-04-29 |
| CVE-2012-4454 | openCryptoki before 2.4.1, when using spinlocks, allows local users to create or set world-writable permissions on arbitrary files via a symlink attack on the (1) .pkapi_xpk or (2) .pkcs11spinloc file in /tmp. | [email protected] | 2.9 | 0.66% | 2012-10-10 | 2026-04-29 |
