# Integer underflow in Adobe Flash Player before 11.7.700.261 and 11.8.x through 12.0.x before 12.0.0.44 on Windows…

Adobe Flash Player has an integer underflow flaw that lets a remote attacker run arbitrary code. CISA lists it as actively exploited in the wild.

_Summary, check and fix written by a model from the sources; labelled as such._
