Microsoft released patches addressing versions from Windows 10 1607 through Windows 11 26H1 and Server 2012 R2 through Server 2025. CVSS 7.0 rating reflects high attack complexity; no public exploit identified at time of analysis. EPSS data not prov
Local privilege escalation in Windows Win32K graphics subsystem (Win32K-GRFX) allows authenticated attackers with low privileges to gain SYSTEM-level access by exploiting a race condition during concurrent resource access. Affects all supported Windows 10, Windows 11, and Windows Server versions from 2012 through 2025. Microsoft has released patches addressing this CWE-362 synchronization flaw. No public exploit identified at time of analysis, though the local attack vector and high complexity (
Local privilege escalation in Windows SSDP Service affects all supported Windows 10, Windows 11, and Windows Server versions from 2012 through 2025 via a race condition vulnerability. Authenticated local users with low privileges can exploit improper synchronization in shared resource access to gain SYSTEM-level privileges, achieving full system compromise. Vendor-released patches are available across all affected versions. No public exploit identified at time of analysis, though the local attack vector and high impact warrant priority patching on multi-user or sensitive systems.
Double free vulnerability in Microsoft Brokering File System enables local privilege escalation on Windows 11 (versions 24H2, 25H2, 26H1) and Windows Server 2025. Low-privileged authenticated users can exploit memory corruption (CWE-415) to gain SYSTEM-level access with high attack complexity. Microsoft has released patches addressing builds prior to 10.0.26100.32690 (24H2/Server 2025), 10.0.26200.8246 (25H2), and 10.0.28000.1836 (26H1). EPSS score of 0.04% (11th percentile) and SSVC assessment of no active exploitation suggest low immediate threat despite 7.0 CVSS score, though CISA classifies technical impact as total (complete system compromise).
Local privilege escalation in Windows SSDP Service (all Windows 10, 11, and Server versions from 2012 onwards) enables low-privileged authenticated users to gain SYSTEM-level access by exploiting a race condition in shared resource handling.

Heap use-after-free in libsixel 1.8.7 and earlier allows local code execution when processing malicious animated GIF files through the sixel_helper_load_image_file() API with multi-frame callbacks. The vulnerability triggers when gif_init_frame() unconditionally frees and reallocates frame->pixels between frames while client code retains references via the documented sixel_frame_ref() API, creating dangling pointers confirmed by AddressSanitizer. Fixed in version 1.8.7-r1. No public exploit iden
