Normal user on macOS(with SIP enabled) can locally exploit this vulnerabilities chain to elevate privilege to the ROOT without a user being aware. The only requirement needed to trigger the vulnerabilities is that Adobe Acrobat Reader DC has been installed. Today, Adobe Acrobat Reader DC for macOS patched three critical vulnerabilities(CVE-2020-9615, CVE-2020-9614, CVE-2020-9613) I reported.
