Latest Message<\/th>\nTitle: Admins may receive false positive indications in Microsoft Defender vulnerability management for a specific app<\/p>\n

User impact: Admins may receive false positive indications in Microsoft Defender vulnerability management for a specific app.<\/p>\n

Current status: We’re working to validate our fix to ensure its efficacy prior to deploying it to the affected infrastructure. We’re expecting to provide deployment timeline by our next scheduled update.<\/p>\n

Scope of impact: Some admins expecting to receive indications of vulnerabilities in Microsoft Defender for Endpoint for devices with a specific app may be impacted.<\/p>\n

Start time: Monday, July 14, 2025, at 4:00 AM UTC<\/p>\n

Root cause: A configuration error in our detection model has resulted in Acrobat Reader executables being marked falsely as Acrobat Reader DC, which is resulting in admins receiving false-positive vulnerability indications.<\/p>\n

Next update by: Thursday, July 24, 2025, at 4:00 PM UTC<\/td>\n<\/tr>\n
