Microsoft has published an advisory for CVE-2025-54105 — a local elevation-of-privilege vulnerability in the Microsoft Brokering File System (BFS) caused by a concurrency bug (race condition) that can be exploited by an authenticated local user to gain elevated rights on the host. Background The...

CVE-2025-55226 is a locally exploitable race‑condition vulnerability in the Windows Graphics Kernel that allows an authenticated (local) attacker to achieve code execution in kernel context by inducing concurrent access to a shared graphics subsystem resource without proper synchronization. This...

Microsoft’s security portal lists CVE-2025-55228 as a Windows Graphics Component issue in the Win32K — GRFX code path that can be abused by an authenticated local actor through a concurrency/race condition; the flaw is described as allowing execution of attacker-supplied code in kernel context...
