In initAppLinkTypeAndIntent of ChannelImpl.java, there is a possible launch an arbitrary intent due to improper input validation. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation.
AnalysisAI
Local privilege escalation in Android's ChannelImpl.java allows a low-privileged installed application to launch arbitrary intents by exploiting improper input validation in the initAppLinkTypeAndIntent method. Affected versions span Android 14 through 17, including 16-QPR2. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires three concrete prerequisites: (1) a malicious application must be installed on the target Android device running Android 14 through 17 or 16-QPR2; (2) the attacking app must have low-level user privileges (PR:L - a standard installed app context, not requiring system or root access); (3) the user must actively interact with a mechanism that triggers the initAppLinkTypeAndIntent code path (UI:R - e.g., tapping a crafted link, button, or deep-link within the malicious app). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 7.3 (AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H) reflects a realistic threat model: the attack is local, requires a low-privileged installed app, and demands user interaction (e.g., the victim must tap a crafted link or trigger an in-app action). … 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) corresponding to the September 2026 Android Security Bulletin, available at https://source.android.com/docs/security/bulletin/2026/2026-09-01. … Detailed patch versions, workarounds, and compensating controls in full report. |
