Description
A flaw was found in the drm/amd/display component of the Linux kernel. A missing function hook check could lead to an unspecified dsc eDP issue. The precise impact of this vulnerability is not fully detailed, but it suggests a potential for system instability or unexpected behavior within the display functionality.
Statement
This vulnerability is rated as having a Low impact because exploitation requires local access and is constrained to systems equipped with specific AMD display hardware utilizing embedded DisplayPort (eDP) configurations. In typical enterprise server environments, graphical display adapters and internal panels are rarely present or active, significantly limiting real-world exposure. An unprivileged local user could potentially trigger a kernel crash, resulting in a denial of service without compromising system confidentiality or integrity.
