CVE-2023-21131

Status: ModifiedHigh (7.8)—

In checkKeyIntentParceledCorrectly() of ActivityManagerService.java, there is a possible bypass of Parcel Mismatch mitigations due to a logic error in the code. This could lead to local escalation of privilege and the ability to launch arbitrary activities in settings with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-11 Android-12 Android-12L Android-13Android ID: A-265015796

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).
