CVE-2026-64219

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Validate payload length and link_index in dc_process_dmub_aux_transfer_async [Why&How] dc_process_dmub_aux_transfer_async() copies payload->length bytes into a 16-byte stack buffer (dpaux.data[16]) guarded only by an ASSERT(), which is a no-op in release builds. If a caller ever passes length > 16 this results in a stack buffer overflow via memcpy. Additionally, link_index is used to dereference dc->links[] w
