patched.");

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

  - LLVM before 18.1.3 generates code in which the LR register can be overwritten without data being saved to
    the stack, and thus there can sometimes be an exploitable error in the flow of control. This affects the
    ARM backend and can be demonstrated with Clang. NOTE: the vendor perspective is we don't have strong
    objections for a CVE to be created ... It does seem that the likelihood of this miscompile enabling an
    exploit remains very low, because the miscompile resulting in this JOP gadget is such that the function is
    most likely to crash on most valid inputs to the function. So, if this function is covered by any testing,
    the miscompile is most likely to be discovered before the binary is shipped to production.
    (CVE-2024-31852)

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