The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-104540 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    afs: Fix netns teardown to cancel the preallocation charger

    Fix the teardown of an afs network namespace to make sure it cancels the     work item that keeps the preallocated rxrpc call/conn/peer queue charged     before incoming calls are disabled (i.e. listen 0).

    Also, if net->live is false because the afs netns is being deleted, make     afs_charge_preallocation() skip charging and make afs_rx_new_call() avoid     requeuing the charger.

    (This was found by AI review).

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

An update of the linux package has been released.
