Out-of-bounds read in Windows BitLocker allows an authorized attacker to elevate privileges over a network.
AnalysisAI
Privilege escalation via out-of-bounds read in Windows BitLocker affects a broad swath of Microsoft operating systems from Windows Server 2012 through Windows Server 2025 and Windows 10/11 across multiple feature updates. A low-privileged network-authenticated attacker who can induce user interaction can trigger CWE-125 memory reads beyond buffer boundaries in the BitLocker component, ultimately achieving elevation of privileges with full confidentiality, integrity, and availability impact (CVSS 8.0). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a low-privileged authenticated account on the network (CVSS PR:L, AV:N) - anonymous unauthenticated access is not sufficient. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.0 score with vector AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H reflects a meaningful but constrained threat: exploitation requires a low-privileged authenticated account and user interaction (UI:R), which prevents fully automated mass exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the Microsoft-released cumulative update patches for each affected Windows version as detailed in the MSRC advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-69458. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: conduct an inventory of all Windows Server (2012-2025) and Windows 10/11 systems to understand deployment scale and identify systems managing sensitive data. …
