CVE-2025-36122: IBM® Db2® is vulnerable to a denial of service with a specially crafted query when stmtheap is set to automatic

MediumCVSS 6.5 · v3.1—No exploit No fix recorded

Noroxi assessment

Priority: Monitor (action score 26/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.24% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

IBM Db2 11.5.0 through 11.5.9, and 12.1.0 through 12.1.3 for Linux, UNIX and Windows (includes DB2 Connect Server) could allow an authenticated user to cause a denial of service using a specially crafted SQL query due to improper allocation of system resources.
