CVE-2026-83771

Summary

A use-after-free vulnerability in Windows Camera Frame Server Monitor allows remote attackers to escalate privileges on adjacent networks. This occurs when the camera frame server monitor improperly handles memory after it has been freed, potentially leading to arbitrary code execution with elevated privileges.

Exploitability

Exploitation requires an attacker on an adjacent network with access to the camera frame server monitor service, making it moderately difficult but possible with proper network positioning and timing.

Blast radius

If exploited, this vulnerability could allow attackers to gain full system privileges on affected Windows systems, potentially compromising entire networks through lateral movement and privilege escalation.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Disable the Camera Frame Server Monitor service or restrict network access to port 50000 (the default port for camera frame server) from untrusted networks until a patch is available.
