CVE-2022-20489

Status: ModifiedHigh (7.8)—

In many functions of AutomaticZenRule.java, there is a possible failure to persist permissions settings due to resource exhaustion. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-10 Android-11 Android-12 Android-12L Android-13Android ID: A-242703460

CVSS
