CVE-2026-26178
Published: 14 April 2026
Description
Integer size truncation in Windows Advanced Rasterization Platform (WARP) allows an unauthorized attacker to elevate privileges locally.
Mitigating Controls (NIST 800-53 r5)AI
Directly addresses the CVE by requiring timely identification, reporting, and remediation of the integer truncation flaw in WARP through vendor patches.
Mitigates privilege escalation impact by ensuring WARP and related processes operate with least privileges necessary, limiting unauthorized access post-exploitation.
Implements memory protections such as non-executable memory and address randomization to hinder exploitation of the integer truncation vulnerability for code execution and privilege escalation.
Security SummaryAI
CVE-2026-26178 is an integer size truncation vulnerability (CWE-190, CWE-681) in the Windows Advanced Rasterization Platform (WARP), a component of Microsoft Windows. Published on 2026-04-14, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact.
An unauthorized attacker can exploit this flaw locally to elevate privileges. The attack requires user interaction and no prior privileges, with a network attack vector enabling low-complexity exploitation that achieves high confidentiality, integrity, and availability impacts through privilege escalation.
