In resolveActivity of ActivityStarter.java, there is a possible way to perform Intent Redirection attacks 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.
AnalysisAI
Local privilege escalation in Android 16, 16-QPR2, and 17 is possible via Intent Redirection by exploiting a logic error in ActivityStarter.java's resolveActivity method. A locally-installed malicious application with basic user privileges can craft or intercept Intents to gain unauthorized access to protected system components, achieving full confidentiality, integrity, and availability compromise of the device without requiring any user interaction after installation. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must achieve installation of a malicious application on the target Android device; the app requires only standard user-level privileges (PR:L) - no root, device administrator rights, or special permissions are needed prior to exploitation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.8 score with vector AV:L/AC:L/PR:L/UI:N accurately characterizes the attack surface: a local malicious application with standard user privileges can exploit the flaw without any post-installation user interaction, achieving full C:H/I:H/A:H impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the Android Security Patch Level (SPL) 2026-09-01 or later as detailed in the Android Security Bulletin at https://source.android.com/docs/security/bulletin/2026/2026-09-01. … Detailed patch versions, workarounds, and compensating controls in full report. |
