Use after free in Windows TCP/IP allows an authorized attacker to elevate privileges over a network.
AnalysisAI
Use-after-free in the Windows TCP/IP driver allows a network-adjacent low-privileged authenticated attacker to escalate privileges to SYSTEM on affected Windows 10, Windows 11, and Windows Server 2019-2025 installations. The CVSS:3.1 vector (AV:N/AC:H/PR:L/UI:R) indicates exploitation requires high attack complexity and user interaction, consistent with a race-condition-triggered UAF in the kernel networking stack. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must have an existing low-privilege account on the network (PR:L) and the ability to send TCP/IP traffic to the target system over the network (AV:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 7.1 score with vector AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H reflects a moderate-to-high priority: the network attack vector and full C/I/A impact are significant, but AC:H (race condition timing) and UI:R (victim interaction required) meaningfully raise the bar for 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 Security Update released for this vulnerability, available via Windows Update, WSUS, or Microsoft Update Catalog. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Windows 10, Windows 11, Windows Server 2019, 2022, and 2025 systems and confirm patch availability through Microsoft update channels. …
