CVE-2024-31874

Local denial of service via uninitialized variables

Published Apr 10, 2024 · Updated Nov 3, 2025

Use of uninitialized variables in IBM Security Verify Access Appliance 10.0.0 through 10.0.7 allows local users to cause a service interruption. The public record identifies IBM's Python deployment-script repository as the locus but does not disclose which variable is consumed before initialization. Execution of the affected deployment scripts on the local management host is required, and the reported consequence is availability loss only.
