    implementation. A local attacker can exploit this, to login to the account of a previously logged in user
    without valid credentials. (CVE-2019-8803)

  - An out-of-bounds read error exists in the IOGraphics component due to improper bounds checking. A local
    attacker can exploit this, to cause unexpected system termination or to read kernel memory.
