According to the July 2019 Android Security Bulletin, there were no reports of active exploitation or abuse of these vulnerabilities.

Two privilege escalation flaws

Two privilege escalation flaws in the Android system were patched in the July 2019 security patch.

  • The first EoP flaw tracked as CVE-2019-2112 in the Android system impacts AOSP versions 8.0, 8.1, and 9.
  • The second EoP flaw tracked as CVE-2019-2113 impacts only the AOSP version 9.0.

Other security flaws

The other 31 vulnerabilities patched in this security update include information disclosure impacting the Android system, framework, library, media framework, Qualcomm components, and Qualcomm closed-source components.
