In addCreatorToken of ActivityManagerService.java, there is a possible Intent Redirection Bypass 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
Intent redirection bypass in Android's ActivityManagerService enables a low-privileged local app to escalate privileges and gain full device access without any user interaction. The logic error in addCreatorToken of ActivityManagerService.java corrupts the creator-token mechanism that governs Intent origin and authority, allowing a malicious app to redirect Intents to system-protected components that should be inaccessible to it. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires a malicious app installed on the target device with standard low-privileged user-space permissions (CVSS AV:L/PR:L) - this is the primary gating condition. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.8 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) accurately characterises a local privilege escalation that requires only a low-privileged installed app with no user interaction after installation; attack complexity is low, meaning the logic error is straightforward to exploit once understood. … 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 September 2026 Android Security Bulletin patch addressing CVE-2026-28599, published by Google at https://source.android.com/docs/security/bulletin/2026/2026-09-01. … Detailed patch versions, workarounds, and compensating controls in full report. |
