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\u2019ve confirmed the fix is functioning as intended and have begun rolling it out to the remaining affected environments. We expect the deployment to be completed by Sunday, 27 July 2025.<\/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: Sunday, July 27, 2025, at 10:30 AM UTC<\/td>\n<\/tr>\n
