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

  - net: slip: serialize receive against buffer reallocation sl_realloc_bufs() replaces rbuff and updates     buffsize while holding sl->lock. slip_receive_buf() reads those fields and writes through rbuff without     holding the lock. An MTU change can therefore race with receive processing. An MTU shrink can expose the     new smaller rbuff with the old larger bound, causing an out-of-bounds write. A receive callback which     already loaded the old rbuff can instead continue writing after that buffer has been freed. Serialize     receive processing with sl_realloc_bufs() by holding sl->lock while consuming each receive batch.
    (CVE-2026-68143)

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