Summary

CVE-2026-10852 is a medium-severity NULL Pointer Dereference (CWE-476) vulnerability in Ibm I. Its CVSS base score is 5.9 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 22th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SC-5 (Denial-of-service Protection) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

T1499.004 Application or System Exploitation Impact
Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.
attack.mitre.org →
Why these techniques?

Null pointer dereference in public-facing WebSphere web server plug-in directly enables remote DoS via crafted requests (T1499.004) and exploitation of an internet-accessible application (T1190).

Mitigating Controls (NIST 800-53 r5) AI

SC-5 Denial-of-service Protection good match
prevent

Directly mitigates the DoS condition triggered by crafted requests to the WebSphere WebServer Plug-in.

SI-10 Information Input Validation good match
prevent

Validates inbound requests to block the malformed input that produces the CWE-476 NULL pointer dereference.

SI-2 Flaw Remediation partial match
prevent

Requires prompt application of vendor patches that eliminate the NULL pointer flaw in the plug-in.
