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: crypto: authencesn - Do not place     hiseq at end of dst for out-of-place decryption When decrypting data that is not in-place (src != dst),     there is no need to save the high-order sequence bits in dst as it could simply be re-copied from the     source. However, the data to be hashed need to be rearranged accordingly. Thanks, (CVE-2026-43033)

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