There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but Microsoft has released a patch.
Local code execution in Windows GDI+ (the Graphics Device Interface Plus rendering component) affects a broad range of Microsoft Windows client and server releases from Windows 10 1607 through Windows 11 26H1 and Windows Server 2012 through Server 2025. An attacker who convinces a user to open or preview a specially crafted image or document triggers a heap-based buffer overflow (CWE-122) during graphics parsing, yielding arbitrary code execution in the context of the current user. The CVSS 3.1 base score is 7.8 (AV:L/AC:L/PR:N/UI:R); there is no public exploit identified at time of analysis and it is not listed in CISA KEV, but GDI+ image-parsing flaws are historically attractive to attackers.
Local privilege escalation via arbitrary code execution in Microsoft Windows Resilient File System (ReFS) affects a broad range of Windows 10, Windows 11, and Windows Server (2016-2025) builds. An authorized (low-privileged) attacker who can trigger the vulnerable heap allocation path can corrupt heap memory (CWE-122) to run code in the security context of the ReFS driver, yielding full confidentiality, integrity, and availability impact. No public exploit identified at time of analysis, and the flaw is not on the CISA KEV list.
Local code execution in Microsoft's Resilient File System (ReFS) driver allows an authorized (low-privileged) attacker to run arbitrary code with elevated context via a numeric truncation flaw. The bug affects the ReFS component shipped with Windows 10, Windows 11, and Windows Server 2016 through 2025. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; note that the CVE's own tags label it 'Information Disclosure' while the description and CVSS impact (C:H/I:H/A:H) describe full code execution - the code-execution reading should be treated as authoritative.
Local privilege escalation in the Windows Routing and Remote Access Service (RRAS) lets an already-authenticated low-privileged user (PR:L) abuse a symbolic-link/junction resolution flaw (CWE-59) to redirect a privileged file operation and gain SYSTEM-level control on affected Windows 10, Windows 11, and Windows Server 2012-2025 hosts. Microsoft has released patches; there is no public exploit identified at time of analysis and the flaw is not in CISA KEV, with a low EPSS of 0.28% (20th percentile). SSVC rates technical impact as total but marks exploitation as none and not automatable, consistent with a hands-on local escalation rather than a mass-exploitable remote bug.
Local privilege escalation in the Microsoft Windows Universal Disk Format File System driver (udfs.sys) lets an authenticated low-privileged user gain SYSTEM-level control by triggering an integer underflow (CWE-191) while parsing a malicious UDF-formatted volume.
