IBM Db2 for Linux, UNIX and Windows (includes Db2 Connect Server) 11.1 and 11.5 under very specific conditions, could allow a local user to keep running a procedure that could cause the system to run out of memory.and cause a denial of service. IBM X-Force ID: 202267.
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H
- Base score: 5.1
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.25%
- Percentile among all scored CVEs: 16
- Score date: 10/15/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
