CVE-2021-41850

An issue was discovered in Luna Simo PPR1.180610.011/202001031830. A pre-installed app with a package name of com.skyroam.silverhelper writes three IMEI values to system properties at system startup. The system property values can be obtained via getprop by all third-party applications co-located on the device, even those with no permissions granted, exposing the IMEI values to processes without enforcing any access control.
