CVE-2020-12911

Estado: ModificadaMedia (5.5)—

A denial of service vulnerability exists in the D3DKMTCreateAllocation handler functionality of AMD ATIKMDAG.SYS (e.g. version 26.20.15029.27017). A specially crafted D3DKMTCreateAllocation API request can cause an out-of-bounds read and denial of service (BSOD). This vulnerability can be triggered from a non-privileged account.
