Nov 2025: Windows Kernel Elevation of Privilege Vulnerability
CVE-2025-62215 Published on November 11, 2025
Windows Kernel Elevation of Privilege Vulnerability
Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Kernel allows an authorized attacker to elevate privileges locally.
Known Exploited Vulnerability
This Microsoft Windows Race Condition Vulnerability is part of CISA's list of Known Exploited Vulnerabilities. Microsoft Windows Kernel contains a race condition vulnerability that allows a local attacker with low-level privileges to escalate privileges. Successful exploitation of this vulnerability could enable the attacker to gain SYSTEM-level access.
The following remediation steps are recommended / required by December 3, 2025: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
Weakness Types
What is a Race Condition Vulnerability?
The program contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently.
CVE-2025-62215 has been classified to as a Race Condition vulnerability or weakness.
What is a Double-free Vulnerability?
The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations. When a program calls free() twice with the same argument, the program's memory management data structures become corrupted. This corruption can cause the program to crash or, in some circumstances, cause two later calls to malloc() to return the same pointer. If malloc() returns the same value twice and the program later gives the attacker control over the data that is written into this doubly-allocated memory, the program becomes vulnerable to a buffer overflow attack.
CVE-2025-62215 has been classified to as a Double-free vulnerability or weakness.
