To rectify this, the patch introduces a safeguard within the     dbAllocDmapLev() function. A check has been added to verify if leafidx is negative. If it is, the function     immediately returns an I/O error, preventing any further execution that could potentially cause harm.
    Tested via syzbot. (CVE-2023-53485)

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