CVE-2025-21292: Elevation of Privilege in Windows Search Service

This vulnerability allows a local attacker to escalate their privileges on a targeted system. An attacker could potentially gain control over the entire system, install malicious software, steal sensitive data, or disrupt operations. The impact is particularly severe in environments where user accounts have limited privileges, as exploitation could bypass these security controls. While the vulnerability requires local access, it represents a significant risk in scenarios involving insider threats or compromised user accounts.
