CVE-2024-0021

Status: AnalyzedHigh (7.8)—

In onCreate of NotificationAccessConfirmationActivity.java, there is a possible way for an app in the work profile to enable notification listener services due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation.

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).
