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

  - ksmbd: fix tree connection use-after-free in smb2_tree_connect() ksmbd_tree_conn_connect() publishes a new     tree connection in sess->tree_conns with a single reference and returns its pointer to     smb2_tree_connect(). The handler continues to initialize the object and build the response after     publication. A concurrent session logoff can erase the connection and drop that reference, freeing the     object while the handler still uses it. BUG: KASAN: slab-use-after-free in smb2_tree_connect+0xe3d/0xf90     smb2_tree_connect (fs/smb/server/smb2pdu.c:2872) handle_ksmbd_work process_one_work worker_thread kthread     After xa_store() succeeds, take a second reference before releasing tree_conns_lock. The original     reference belongs to the xarray entry and the second belongs to the creating smb2_tree_connect() handler.
    Keep the references balanced in every path: - On normal exit or an error after publication,     smb2_tree_connect() drops its creator reference. Error cleanup also calls ksmbd_tree_conn_disconnect(),     which drops the xarray reference only if it removes the exact entry. - SMB2 TREE_DISCONNECT uses the same     helper to remove the entry and drop its xarray reference. The request's existing lookup reference remains     owned by the request and is released by the existing cleanup. - Session LOGOFF removes each entry and     drops its xarray reference. If it wins the race, later cleanup sees that the entry is gone and does not     drop that reference again. To enforce this ownership, claim the disconnected state and erase the exact     entry atomically under tree_conns_lock. This guarantees one drop for the xarray reference and one drop by     each in-flight user, regardless of which teardown path wins. If logoff removes the entry before     initialization completes, fail the connect instead of marking the detached object TREE_CONNECTED.
    (CVE-2026-89788)

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

The remote Ubuntu 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-9002-1 advisory.

    It was discovered that the io_uring subsystem in the Linux kernel did not properly handle canceled task     work when processing certain wait operations, leading to the operation being performed in the wrong task     context. A local attacker could possibly use this to cause a denial of service (system crash).
