This vulnerability allows a locally authenticated attacker to elevate their privileges on a vulnerable system. The vulnerability exists because the Projected File System improperly handles memory operations. Exploitation of this flaw allows an attacker to execute arbitrary code with elevated privileges. Successful exploitation requires an attacker to have valid credentials on the local system and the ability to execute code. Microsoft assigned a CVSS v3.1 score of 7.8 (HIGH) to this vulnerability. Organizations should apply the provided patch as soon as possible to mitigate the risk.\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 valid local user credentials.\u003c/li\u003e\n\u003cli\u003eThe attacker executes a specially crafted application designed to interact with the Windows Projected File System.\u003c/li\u003e\n\u003cli\u003eThe crafted application triggers the use-after-free vulnerability by causing the Projected File System to access a memory location that has already been freed.\u003c/li\u003e\n\u003cli\u003eThis memory corruption allows the attacker to overwrite critical data structures within the kernel.\u003c/li\u003e\n\u003cli\u003eThe attacker manipulates these data structures to gain control of system execution flow.\u003c/li\u003e\n\u003cli\u003eThe attacker injects malicious code into a privileged process.\u003c/li\u003e\n\u003cli\u003eThe injected code executes with elevated privileges (SYSTEM).\u003c/li\u003e\n\u003cli\u003eThe attacker can now perform actions such as installing programs, viewing, changing, or deleting data, or creating new accounts with full user rights.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-32078 allows a local attacker to elevate their privileges to SYSTEM. This grants the attacker complete control over the compromised system. The attacker can install malware, exfiltrate sensitive data, create new administrator accounts, and perform other malicious activities. This could lead to significant data loss, system downtime, and reputational damage.
