This flaw allows a locally authenticated attacker to achieve privilege escalation on a targeted system. The vulnerability stems from improper synchronization when accessing a shared resource concurrently. Successful exploitation could allow an attacker to execute code with elevated permissions. This vulnerability impacts systems where the Windows User Interface Core is utilized, potentially affecting a wide range of Windows installations. Defenders should prioritize patching to prevent potential exploitation.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker gains local access to a Windows system.\u003c/li\u003e\n\u003cli\u003eAttacker identifies the vulnerable Windows User Interface Core component.\u003c/li\u003e\n\u003cli\u003eAttacker crafts a malicious application or script to trigger the race condition.\u003c/li\u003e\n\u003cli\u003eThe malicious application initiates concurrent access to the shared resource.\u003c/li\u003e\n\u003cli\u003eDue to improper synchronization, the application exploits the race condition to overwrite critical system data.\u003c/li\u003e\n\u003cli\u003eThe overwritten data leads to the attacker gaining elevated privileges.\u003c/li\u003e\n\u003cli\u003eAttacker executes privileged commands or deploys malicious payloads.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-32164 allows a local attacker to escalate their privileges on a Windows system.
