An authenticated local attacker who can trigger the vulnerable NTFS code path can corrupt heap memory (CWE-122) to run arbitrary code, gaining high confidentiality, integrity, and availability impact on the affected system. There is no public exploit identified at time of analysis, and the low EPSS score (0.31%, 23rd percentile) together with CISA SSVC 'Exploitation: none' indicates no observed exploitation, though the total technical impact keeps it patch-worthy.
Local privilege escalation in the Microsoft Windows USB Hub Driver allows an authenticated low-privileged user to elevate to SYSTEM by triggering an untrusted pointer dereference (CWE-822), affecting Windows 10 (1809/21H2/22H2) and Windows Server 2019 through 2025. Successful exploitation yields full confidentiality, integrity, and availability impact on the local host. There is no public exploit identified at time of analysis and the flaw is not listed in CISA KEV, but Microsoft has released a patch.
Local privilege escalation in the Microsoft Windows Kernel lets an authenticated attacker who already has low-privileged code execution on a host elevate to SYSTEM by exploiting a use-after-free (CWE-416) memory corruption. It affects a broad range of supported Windows client and server builds - Windows 10 (1809/21H2/22H2), Windows 11 (24H2/25H2/26H1), and Windows Server 2019/2022/2025 - and Microsoft has released a patch. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, so exploitation appears unproven publicly despite the reliably-exploitable nature of kernel UAF flaws.
Local privilege escalation in the Microsoft Windows Kernel (CWE-122 heap-based buffer overflow) allows an authenticated local attacker to gain SYSTEM-level control across a broad range of currently supported Windows client and server releases, from Windows 10 1607 and Server 2012 through Windows 11 26H1 and Server 2025. Exploitation grants total confidentiality, integrity, and availability impact (CVSS 3.1 7.8, C:H/I:H/A:H). There is no public exploit identified at time of analysis, CISA SSVC lists exploitation as none, and the EPSS score is low at 0.32% (24th percentile), indicating no evidence of active or imminent mass exploitation despite the critical technical impact.
Information disclosure in the Windows Network Policy Server (NPS) SNMP component allows a remote, unauthenticated attacker to read out-of-bounds memory over the network and disclose sensitive process data. The flaw affects a broad range of Windows client and server releases, from Windows 10 1607 and Windows Server 2012 through Windows 11 26H1 and Windows Server 2025. It was reported by Microsoft, a vendor patch is available, and no public exploit has been identified at time of analysis (not listed in CISA KEV).
Local privilege escalation in the Windows Wireless Wide Area Network (WWAN) Service affects all supported Windows 10, Windows 11, and Windows Server builds (2019 through 2025), where a race condition (CWE-362) in access to a shared resource lets an already-authenticated local user win a timing window to gain higher privileges. Microsoft rates it CVSS 7.0 with total technical impact (SSVC), but exploitation requires high attack complexity and there is no public exploit identified at time of analysis. EPSS is low (0.16%, 5th percentile), consistent with the difficulty of reliably winning the race.
Remote information disclosure in the Microsoft Windows Kernel (CWE-125 out-of-bounds read) lets an unauthenticated attacker read kernel memory over a network, per the CVSS AV:N/PR:N vector, affecting a broad range of Windows 10, Windows 11, and Windows Server 2016 through 2025 builds. The flaw carries high confidentiality impact (C:H) with a minor availability side effect and no integrity impact, scoring CVSS 8.2. No public exploit is identified at time of analysis and it is not in CISA KEV, but the network-reachable, no-authentication, no-interaction profile makes it a notable patch priority.
Local privilege escalation in Microsoft Windows (Windows 10 1607 through Windows 11 26H1 and Windows Server 2012 through 2025) arises from a use-after-free memory-corruption flaw (CWE-416) that lets an already-authenticated local user run code at elevated privilege. The CVSS 3.1 base score is 7.8 with a scope-changed vector, and Microsoft has shipped a fix via MSRC. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV, so exploitation is currently theoretical rather than observed.
