CVE-2025-36156 — Ibm Infosphere Data Replication Vsam For Z/Os Remote Source security vulnerability

High CVSS 7.8

IBM InfoSphere Data Replication VSAM for z/OS Remote Source 11.4 is vulnerable to a stack-based buffer overflow, caused by improper bounds checking. A local user with access to the files storing CECSUB or CECRM on the container could overflow the buffer and execute arbitrary code on the system.

Matched remediation archetype

Buffer bounds, memory safety, and memory corruption

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Identify affected native-code versions, build flags, architectures, parsers, codecs, drivers, and input paths in all shipped artifacts.
  • Determine whether untrusted data reaches the affected routine and the process privilege, sandbox, and network exposure.
  • Confirm statically linked, vendored, firmware, and platform-provided copies, not only package-manager records.

Remediate safely

  • Apply the maintained upstream correction or replace the affected component, then rebuild every dependent artifact from clean inputs.
  • Adopt bounds-checked interfaces, validated sizes and integer conversions, clear ownership, and memory-safe components where practical.
  • Enable supported compiler and runtime hardening and add sanitized tests and fuzz regression seeds derived from non-weaponized fixtures.
