CVE-2026-32076 is a high-severity Out-of-bounds Read (CWE-125) vulnerability in Microsoft Windows 11 23H2. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 18.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-16 (Memory Protection) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-32076 is an out-of-bounds read vulnerability (CWE-125) in the Windows Storage Spaces Controller. Published on 2026-04-14T18:17:09.120, it carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and affects the Windows Storage Spaces Controller component in Windows systems.
A local attacker with low privileges (PR:L) can exploit this vulnerability due to its low attack complexity (AC:L) and lack of required user interaction (UI:N). Successful exploitation enables local privilege escalation, resulting in high impacts to confidentiality, integrity, and availability (C:H/I:H/A:H) without changing scope (S:U).

Mitigating Controls (NIST 800-53 r5) AI
Requires timely patching and remediation of the specific out-of-bounds read flaw in Windows Storage Spaces Controller to eliminate the privilege escalation vulnerability.
Implements memory protection mechanisms such as address space layout randomization and data execution prevention that directly mitigate exploitation of out-of-bounds read vulnerabilities like CWE-125.
Enforces least privilege to limit the scope and impact of local privilege escalation even if the out-of-bounds read is triggered by a low-privileged attacker.
