System crashes via out-of-bounds string reads
Published Aug 14, 2025 · Updated Aug 15, 2025
Out-of-bounds reads in Malwarebytes before 4.6.14.326 and before 5.1.5.116 allow remote attackers to crash systems. The string detection utilities read outside intended buffer bounds, but Malwarebytes has not disclosed the exact routine or triggering input. No account or user interaction is required; affected Nebula deployments date from 2020-10-21, and the reported consequence is a system crash.
