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: fuse: fix missing barrier when     checking io-uring readiness fuse_block_alloc() reads fch->initialized and then fch->io_uring.
    fch->io_uring is set before fch->initialized, ordered by the smp_wmb() in fuse_chan_set_intialized(), but     fuse_block_alloc() has no matching read barrier between the two loads. This may lead a CPU to observe     fch->initialized=1 but fch->io_uring=0, and skip the check that blocks request allocation until the io-     uring queues are ready. This can reintroduce the lock-order inversion deadlock that commit 3393ff964e0f     prevents. Add an smp_rmb() barrier to pair with the smp_wmb() in fuse_chan_set_initialized() to prevent     this. (CVE-2026-80859)

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