An update of the linux package has been released.

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: net: qrtr: Avoid potential use after     free in MHI send It is possible that the MHI ul_callback will be invoked immediately following the     queueing of the skb for transmission, leading to the callback decrementing the refcount of the associated     sk and freeing the skb. As such the dereference of skb and the increment of the sk refcount must happen     before the skb is queued, to avoid the skb to be used after free and potentially the sk to drop its last     refcount.. (CVE-2021-46973)

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