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

  - bus: mhi: host: Detect events pointing to unexpected TREs When a remote device sends a completion event to     the host, it contains a pointer to the consumed TRE. The host uses this pointer to process all of the TREs     between it and the host's local copy of the ring's read pointer. This works when processing completion for     chained transactions, but can lead to nasty results if the device sends an event for a single-element     transaction with a read pointer that is multiple elements ahead of the host's read pointer. For instance,     if the host accesses an event ring while the device is updating it, the pointer inside of the event might     still point to an old TRE. If the host uses the channel's xfer_cb() to directly free the buffer pointed to     by the TRE, the buffer will be double-freed. This behavior was observed on an ep that used upstream EP     stack without 'commit 6f18d174b73d (bus: mhi: ep: Update read pointer only after buffer is written)'.
    Where the device updated the events ring pointer before updating the event contents, so it left a window     where the host was able to access the stale data the event pointed to, before the device had the chance to     update them. The usual pattern was that the host received an event pointing to a TRE that is not     immediately after the last processed one, so it got treated as if it was a chained transaction, processing     all of the TREs in between the two read pointers. This commit aims to harden the host by ensuring     transactions where the event points to a TRE that isn't local_rp + 1 are chained. [mani: added stable tag     and reworded commit message] (CVE-2025-39790)

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