CVE-2025-62454 is a heap-based buffer overflow vulnerability in the Windows Cloud Files Mini Filter Driver, a kernel-mode component used to support cloud-backed file operations. The flaw allows a locally authorized attacker to trigger memory corruption through crafted file operations against the driver’s attack surface and elevate privileges on the affected system. Public reporting associates the issue with the cldflt.sys code path and notes that Microsoft assessed exploitation as more likely. The vulnerability is local in nature and affects the Windows Cloud Files Mini Filter Driver rather than a user-mode application, making it relevant as a post-compromise privilege-escalation primitive.
