The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - drm/amd/display: Avoid NULL dereference in dc_dmub_srv error paths In dc_dmub_srv_log_diagnostic_data()     and dc_dmub_srv_enable_dpia_trace(). Both functions check: if (!dc_dmub_srv || !dc_dmub_srv->dmub) and     then call DC_LOG_ERROR() inside that block. DC_LOG_ERROR() uses dc_dmub_srv->ctx internally. So if     dc_dmub_srv is NULL, the logging itself can dereference a NULL pointer and cause a crash. Fix this by     splitting the checks. First check if dc_dmub_srv is NULL and return immediately. Then check     dc_dmub_srv->dmub and log the error only when dc_dmub_srv is valid. Fixes the below:
    ../display/dc/dc_dmub_srv.c:962 dc_dmub_srv_log_diagnostic_data() error: we previously assumed     'dc_dmub_srv' could be null (see line 961) ../display/dc/dc_dmub_srv.c:1167     dc_dmub_srv_enable_dpia_trace() error: we previously assumed 'dc_dmub_srv' could be null (see line 1166)     (CVE-2026-53313)

Note that Nessus relies on the presence of the package as reported by the vendor.
