Vulnerability Data

Vulnerability in the Oracle Database Sharding component of Oracle Database Server. Supported versions that are affected are 19.3-19.22 and 21.3-21.13. Easily exploitable vulnerability allows high privileged attacker having DBA privilege with network access via Oracle Net to compromise Oracle Database…

more

Sharding. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Database Sharding. CVSS 3.1 Base Score 2.4 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:N/I:N/A:L).

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing or incorrect resource releases after code is written.

Engineering principles can require explicit resource acquisition/release patterns that stop improper shutdown from being introduced.

Priority-based resource allocation limits the blast radius when released resources are not returned to the pool.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

blocks

documenting procedures for secure operation, error handling, restart/recovery and resource management (including references to 8.13/8.18) is a governance and dependency control that does not itself stop exploitation of a resource-shutdown flaw; any prevention would require other controls (e.g. code changes or runtime enforcement) configured to act on it

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-404, a class-level weakness, and none of its children carries one either.
