Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue concerns the Linux kernel, specifically the drm/amd/display component for DCN303. It involves checking the correct bounds for stream encoder instances to prevent potential out of bounds access.
