When re-configuring the mobile phone using the factory reset protection (FRP) function, an attacker can disable the boot wizard by enable the talkback function. As a result, the FRP function is bypassed.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
