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

  - nfsd: close shrinker/GC/fsnotify vs per-net shutdown race in filecache The shrinker, GC worker, and     fsnotify/lease callbacks can unhash an nfsd_file from the rhashtable and then call     nfsd_file_dispose_list_delayed() to move it to the per-net dispose list. If nfsd_file_cache_shutdown_net()     runs concurrently, its rhashtable walk misses the already-unhashed file, and its drain of the per-net     dispose list can run before the file has been queued. The file then sits on the per-net list with no     thread to drain it, leaking both the file and its associated state. The GC worker and shrinker already     hold nfsd_gc_lock while walking the LRU, but in the original code they release it before calling     nfsd_file_dispose_list_delayed(). The fsnotify/lease path (nfsd_file_close_inode) has no synchronization     at all. Fix this by: 1. Widening nfsd_gc_lock in both nfsd_file_gc() and nfsd_file_lru_scan() to cover the     nfsd_file_dispose_list_delayed() call. 2. Wrapping nfsd_file_close_inode() in nfsd_gc_lock so that all     three callers of nfsd_file_dispose_list_delayed() hold the lock. 3. Adding a     spin_lock/unlock(nfsd_gc_lock) barrier in nfsd_file_cache_shutdown_net() after the purge, so that any in-     progress disposal has fully completed before the per-net list is drained. All operations inside the lock     are non-sleeping (rhashtable lookups, atomic bit/refcount ops, list moves, svc_wake_up), so the spinlock     is appropriate. (CVE-2026-89667)

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