This flaw allows an attacker with local access and low privileges to escalate their privileges on the system. The vulnerability arises from improper memory management within the tdx.sys driver. Exploitation of this issue could allow the attacker to execute arbitrary code with elevated privileges. This vulnerability was published on April 14, 2026, and is documented by Microsoft as part of their regular security updates. Successful exploitation grants the attacker greater control over the compromised system and may facilitate further malicious activities.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker gains initial access to the target system with low privileges.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious program to interact with the TDI Translation Driver (tdx.sys).\u003c/li\u003e\n\u003cli\u003eThe malicious program triggers the use-after-free condition within tdx.sys by freeing a memory object and then attempting to access it again.\u003c/li\u003e\n\u003cli\u003eThe vulnerable driver attempts to access the freed memory, leading to a controlled memory corruption.\u003c/li\u003e\n\u003cli\u003eThe attacker leverages the memory corruption to overwrite critical system data structures.\u003c/li\u003e\n\u003cli\u003eThe attacker manipulates privilege-related fields in the overwritten data structures.\u003c/li\u003e\n\u003cli\u003eThe attacker executes code that leverages the modified privilege levels.\u003c/li\u003e\n\u003cli\u003eThe attacker successfully elevates their privileges to SYSTEM.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-27908 allows a local attacker to elevate privileges to SYSTEM. This gives the attacker complete control over the affected system, allowing them to install programs; view, change, or delete data; or create new accounts with full user rights. The vulnerability impacts any Windows system where the TDI Translation Driver is enabled. This privilege escalation could be a stepping stone for more extensive attacks within a corporate network.\u003c/p\u003e\n\u003ch2 id=\"recommendation\"\u003eRecommendation\u003c/h2\u003e\n\u003cul\u003e\n\u003cli\u003eApply the security update provided by Microsoft to patch CVE-2026-27908 as soon as possible.
