The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-989571 advisory.

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

    usb: typec: tcpm: cancel vdm and state machine hrtimer when unregister tcpm port

    A pending hrtimer may expire after the kthread_worker of tcpm port     is destroyed, see below kernel dump when do module unload, fix it     by cancel the 2 hrtimers.
