CVE-2020-0027

Status: ModifiedHigh (7.8)—

In HidRawSensor::batch of HidRawSensor.cpp, there is a possible out of bounds write due to an unexpected switch fallthrough. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-8.0 Android-8.1 Android-9 Android-10Android ID: A-144040966

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).
