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: x86/sgx: Resolves SECS reclaim vs.
    page fault for EAUG race The SGX EPC reclaimer (ksgxd) may reclaim the SECS EPC page for an enclave and     set secs.epc_page to NULL. The SECS page is used for EAUG and ELDU in the SGX page fault handler. However,     the NULL check for secs.epc_page is only done for ELDU, not EAUG before being used. Fix this by doing the     same NULL check and reloading of the SECS page as needed for both EAUG and ELDU. The SECS page holds     global enclave metadata. It can only be reclaimed when there are no other enclave pages remaining. At that     point, virtually nothing can be done with the enclave until the SECS page is paged back in. An enclave can     not run nor generate page faults without a resident SECS page. But it is still possible for a #PF for a     non-SECS page to race with paging out the SECS page: when the last resident non-SECS page A triggers a #PF     in a non-resident page B, and then page A and the SECS both are paged out before the #PF on B is handled.
    Hitting this bug requires that race triggered with a #PF for EAUG. Following is a trace when it happens.

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