Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description An array index out of bounds error exists in the DCN32 DML component of the AMD display driver. The issue occurs within the vba vars st{} structure of the drivers/gpu/drm/amd/display/dc/dml/display mode vba.h module, where the LinkCapacitySupport array is indexed using the number of voltage states instead of the maximum number of DPPs. This improper indexing can be exploited to cause a denial of service.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
