CVE-2008-4250: Legacy Windows Server Service RPC remote code execution
The legacy Windows Server Service RPC flaw permits unauthenticated code execution on Windows 2000, XP and Server 2003; Vista and Server 2008 require authentication. Historical patching does not replace retirement or investigation of unsupported assets.
CVE-2009-1537: Legacy DirectShow QuickTime parsing RCE
Crafted media can exploit Microsoft's legacy DirectShow QuickTime parser and run code with the user's rights. This is not blanket exposure of Apple's QuickTime application; match the historical Windows component and replace unsupported systems.
CVE-2010-0249: Legacy Internet Explorer use-after-free RCE
CVE-2010-0249 can execute code through crafted web content in legacy Internet Explorer. Microsoft's original bulletin reported limited attacks; the 2026 KEV addition is separate history, not a new disclosure or justification for retaining unsupported systems.
CVE-2010-0806: Legacy Internet Explorer use-after-free RCE
Crafted content viewed in affected legacy Internet Explorer versions can run code with the user's rights. MS10-018 documents the historical fix; it does not restore support, so surviving unsupported browser and platform combinations require retirement.
CVE-2026-41091: Microsoft Malware Protection Engine privilege escalation
A link-following flaw in Microsoft Malware Protection Engine can let an authorized local attacker gain SYSTEM privileges. Verify the installed engine update and review endpoint telemetry; this is not unauthenticated remote takeover.
CVE-2026-45498: Microsoft Defender local denial of service
The exploited Microsoft Defender flaw can interrupt protection through denial of service. Verify the Antimalware Platform update on each endpoint and examine Defender health telemetry; a currently healthy service does not rule out earlier disruption.
CVE-2026-0257: PAN-OS GlobalProtect authentication bypass
GlobalProtect authentication-override cookies can permit unauthorized VPN connections under the affected certificate configuration. Coordinate fixes across every cookie-generating and accepting portal or gateway, including hybrid Prisma Access deployments, and investigate sessions separately from patching.
CVE-2025-48595: Android Framework privilege escalation
Android Framework integer overflow can enable local privilege escalation beyond normal device permissions. Install the OEM security update and verify its reported patch level; this platform issue is not limited to Pixel devices.
CVE-2026-50751: Check Point deprecated IKEv1 VPN authentication bypass
Check Point's exploited VPN bypass requires Remote Access or Mobile Access, IKEv1, accepted legacy clients and no mandatory machine certificate. Gateway and Spark remediation differ; review suspicious VPN sessions separately from installing the appropriate fix.
CVE-2026-20245: Cisco Catalyst SD-WAN authenticated root privilege escalation
An attacker with netadmin privileges can use a crafted file to gain root on affected SD-WAN control components. Preserve admin-tech before upgrading, then inspect indicators and verify downstream edge-device configuration.
