Red Hat Security Advisory: opencryptoki security update
The opencryptoki packages contain version 2.11 of the PKCS#11 API, implemented for IBM Cryptocards, such as IBM 4764 and 4765 crypto cards. These packages includes support for the IBM 4758 Cryptographic CoProcessor (with the PKCS#11 firmware loaded), the IBM eServer Cryptographic Accelerator (FC 4960 on IBM eServer System p), the IBM Crypto Express2 (FC 0863 or FC 0870 on IBM System z), and the IBM CP Assist for Cryptographic Function (FC 3863 on IBM System z). The opencryptoki packages also bring a software token implementation that can be used without any cryptographic hardware. These packages contain the Slot Daemon (pkcsslotd) and general utilities. Security Fix(es): * openCryptoki: openCryptoki: Privilege Escalation or Data Exposure via Symlink Following (CVE-2026-23893) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
AI Analysis
Technical Summary
The opencryptoki packages, which provide PKCS#11 API support for IBM cryptographic hardware and software tokens in Red Hat Enterprise Linux 10, contain a vulnerability identified as CVE-2026-23893. This vulnerability allows privilege escalation or data exposure through symlink following, classified under CWE-59. Red Hat Product Security has rated this issue as moderate severity and released updated opencryptoki packages (version 3.25.0-5.el10_1.2) to fix the problem. The update is applicable to Red Hat Enterprise Linux 10 and related CodeReady Linux Builder products across multiple CPU architectures including x86_64, s390x, ppc64le, and aarch64. The vendor advisory provides detailed instructions for applying the update and references the CVE for further information.
Potential Impact
The vulnerability could allow an attacker to escalate privileges or expose sensitive data by exploiting symlink following in the opencryptoki packages. This impacts systems using opencryptoki for cryptographic operations with IBM cryptographic hardware or software tokens. The issue is rated moderate severity by Red Hat Product Security. No known exploits in the wild have been reported at this time.
Mitigation Recommendations
Red Hat has released updated opencryptoki packages (version 3.25.0-5.el10_1.2) that address CVE-2026-23893. Users of Red Hat Enterprise Linux 10 and related CodeReady Linux Builder products should apply these updates promptly following Red Hat's official guidance at https://access.redhat.com/articles/11258. No alternative mitigations are specified; applying the vendor-provided update is the recommended remediation.
