Mojave, 10.15.x prior to 10.15.7 Supplemental Update Catalina, or 11.x prior to 11.2.1 Big Sur. It is, therefore,
affected by multiple vulnerabilities, including the following:

  - An out-of-bounds-write vulnerability caused by insufficient input validation that allows an application
    to execute arbitrary code with kernel privileges. (CVE-2021-1805)

  - A race condition due to insufficient validation that allows an application to execute arbitrary code with
    kernel privileges. (CVE-2021-1806)

  - A local privilege elevation vulnerability in sudo caused by a heap-based buffer overflow. (CVE-2021-3156)
