Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

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

  - In the Linux kernel, the following vulnerability has been resolved: drm/display/dp_mst: Add protection     against 0 vcpi When releasing a timeslot there is a slight chance we may end up with the wrong payload     mask due to overflow if the delayed_destroy_work ends up coming into play after a DP 2.1 monitor gets     disconnected which causes vcpi to become 0 then we try to make the payload = ~BIT(vcpi - 1) which is a     negative shift. VCPI id should never really be 0 hence skip changing the payload mask if VCPI is 0.
