Technical details
The vulnerability stems from the use of a broken or risky cryptographic algorithm for encrypting sensitive data in IBM Enterprise Records. An attacker with local access to the system can exploit this weakness to decrypt protected information. The vulnerability requires local access rather than network access, limiting the threat surface to users or processes with direct system permissions. A patch or update is expected from IBM to replace the weak algorithm with a secure cryptographic implementation. The CVE-2026-81859 identifier tracks this issue.
