CVE-2024-40655

Status: ModifiedHigh (7.8)—

In bindAndGetCallIdentification of CallScreeningServiceHelper.java, there is a possible way to maintain a while-in-use permission in the background due to a permissions bypass. 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).
