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

  - xhci: sideband: don't dereference freed ring when removing sideband endpoint     xhci_sideband_remove_endpoint() incorrecly assumes that the endpoint is running and has a valid transfer     ring. Lianqin reported a crash during suspend/wake-up stress testing, and found the cause to be     dereferencing a non-existing transfer ring 'ep->ring' during xhci_sideband_remove_endpoint(). The endpoint     and its ring may be in unknown state if this function is called after xHCI was reinitialized in resume     (lost power), or if device is being re-enumerated, disconnected or endpoint already dropped. Fix this by     both removing unnecessary ring access, and by checking ep->ring exists before dereferencing it. Also make     sure endpoint is running before attempting to stop it. Remove the xhci_initialize_ring_info() call during     sideband endpoint removal as is it only initializes ring structure enqueue, dequeue and cycle state values     to their starting values without changing actual hardware enqueue, dequeue and cycle state. Leaving them     out of sync is worse than leaving it as it is. The endpoint will get freed in after this in most usecases.
    If the (audio) class driver want's to reuse the endpoint after offload then it is up to the class driver     to ensure endpoint is properly set up. (CVE-2026-23009)

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