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

  - KEYS: trusted: Fix TPM teardown ordering trusted_tpm_exit() drops the TPM chip reference and frees the     digest array before unregistering the trusted key type. key_type_lookup() holds key_types_sem for reading     until the key operation finishes, while unregister_key_type() takes it for writing. It therefore provides     the synchronization point that must precede backend teardown. The current order permits this interleaving:
    CPU 0 CPU 1 trusted_tpm_exit() key_type_lookup(trusted) put_device(&chip->dev) trusted_tpm_seal()     kfree(digests) pcrlock() unregister_key_type() tpm_pcr_extend(..., digests) CPU 1 can consequently     dereference the freed digest array. The chip can also be released before callbacks stop using it.

    __do_sys_delete_module+0x346/0x510 Move unregister_key_type() before releasing either resource. This stops     new lookups and waits for in-flight key operations to finish before the backend state is destroyed.
    (CVE-2026-89763)

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