Use after free in Windows Wireless Networking allows an authorized attacker to elevate privileges locally.
AnalysisAI
Use-after-free in the Windows Wireless Networking subsystem enables a locally authenticated low-privileged attacker to escalate to full system privileges on a wide range of Windows 10, Windows 11, and Windows Server editions. The vulnerability carries CVSS 7.0 (AV:L/AC:H/PR:L) reflecting that exploitation is locally constrained and requires navigating high-complexity timing conditions typical of UAF race conditions, but the resulting impact is complete C/I/A compromise. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must have a valid local user account with at least low-privilege (standard user) access on the target Windows system - PR:L in the CVSS vector confirms this is not an unauthenticated attack. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world exploitation risk is moderate-to-high in priority terms given Windows' ubiquitous deployment, but the per-instance exploitation difficulty is meaningful. … 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 security update for the relevant Windows version immediately via Windows Update or WSUS - exact target build numbers by SKU are listed in the affected products section above. … Detailed patch versions, workarounds, and compensating controls in full report. |
