CVE-2026-23893 1 Opencryptoki Project 1 Opencryptoki 2026-01-22 6.8 Medium
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. When run as root, the base code handling token directory file access, as well as several openCryptoki tools used for administrative purposes, may reset ownership or permissions on existing files inside the token directories. An attacker with token-group membership can exploit the system when an administrator runs a PKCS#11 application or administrative tool that performs chown on files inside the token directory during normal maintenance. This issue is fixed in commit 5e6e4b4, but has not been included in a released version at the time of publication.
CVE-2026-22791 3 Ibm, Linux, Opencryptoki Project 3 Aix, Linux, Opencryptoki 2026-01-14 6.6 Medium
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.
CVE-2024-0914 2 Opencryptoki Project, Redhat 3 Opencryptoki, Enterprise Linux, Rhel Eus 2025-11-20 5.9 Medium
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.
CVE-2012-4454 1 Opencryptoki Project 1 Opencryptoki 2025-04-11 N/A
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.
CVE-2012-4455 1 Opencryptoki Project 1 Opencryptoki 2025-04-11 N/A
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/.
CVE-2021-3798 2 Opencryptoki Project, Redhat 2 Opencryptoki, Enterprise Linux 2024-11-21 5.5 Medium
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.
