CVE-2023-40116

Status: ModifiedHigh (7.8)—

In onTaskAppeared of PipTaskOrganizer.java, there is a possible way to bypass background activity launch restrictions 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 not 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).
