Windows Secure Boot bypass across Windows 10 version 1809 through Windows 11 version 26H1 and multiple Windows Server editions allows an authorized local administrator to circumvent boot-time integrity protections by exploiting a non-updateable boot chain component. A successful attacker can subvert the UEFI Secure Boot trust chain to load unsigned or malicious code at the pre-OS stage, enabling persistent bootkit or rootkit implantation that survives OS reinstallation. No public exploit code has been identified and CISA SSVC reports no active exploitation, though the SSVC technical impact rating of 'total' correctly reflects full defeat of the boot integrity boundary.
Windows Filtering Platform (WFP) on affected Windows 10, Windows 11, and Windows Server releases exposes an improper access control flaw (CWE-284) that enables a locally authenticated, low-privileged attacker to bypass a host-based security feature. The bypass is limited to confidentiality and integrity impacts (no availability), scoped to the vulnerable system, and requires no user interaction once local execution is established. No public exploit code exists and CISA has not added this to the KEV catalog; EPSS at 0.04% (11th percentile) and SSVC exploitation status of 'none' corroborate the low probability of near-term opportunistic weaponization.
Null pointer dereference in the Windows LDAP (Lightweight Directory Access Protocol) component enables a low-privileged local attacker to crash the LDAP service, causing a denial of service on all affected Windows 10, Windows 11, and Windows Server releases. The vulnerability carries a CVSS 3.1 score of 5.5 with a strictly local attack vector (AV:L/PR:L), confining impact to availability only - no data exfiltration or code execution is possible. With EPSS at 0.04% (11th percentile), SSVC exploitation status of 'none,' no KEV listing, and no public exploit identified, real-world exploitation risk is currently low despite the enormous Windows install base.
Privilege escalation via double free in the Windows Rich Text Edit Control (RichEdit) affects an exceptionally broad range of Microsoft platforms, spanning Windows 10 versions 1607 through 22H2, all current Windows 11 branches through 26H1, and Windows Server 2012 through Server 2025. A low-privileged local attacker who can induce user interaction with crafted RTF content can corrupt heap memory to achieve full compromise of confidentiality, integrity, and availability - consistent with the SSVC 'total technical impact' rating. No public exploit code exists and no active exploitation has been identified (not in CISA KEV), and the EPSS score of 0.05% at the 16th percentile reflects a minimal current exploitation signal; however, the sheer scale of the affected Windows install base keeps this relevant for enterprise patch cadence. A notable discrepancy exists: the CVE tags classify this as 'Information Disclosure,' which conflicts with Microsoft's own description of local privilege elevation - the CVSS C:H/I:H/A:H impact metrics and SSVC total-impact rating support the privilege escalation characterization, suggesting the tag is erroneous.
