AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Local vector confirmed by description; PR:L because basic app execution suffices; full C/I/A:H reflects kernel-level compromise from privilege escalation.

In multiple functions of iommu.c, there is a possible out of bounds read/write due to improper input validation. 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 the Android kernel's IOMMU subsystem (iommu.c) allows any process with basic user-level execution to gain full kernel privileges through out-of-bounds memory read/write triggered by improper input validation across multiple functions. The CVSS vector (AV:L/AC:L/PR:L/UI:N) confirms low attack complexity with no user interaction required, making this a reliable local privilege escalation primitive for post-compromise chains or malicious apps. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires local code execution on the target Android device at a minimum of standard app-level (PR:L) process privileges - any installed app or shell user can attempt exploitation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.8 score with AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H accurately characterizes the real-world risk: a locally-executing app or shell process with ordinary user privileges can reliably trigger the flaw without any special system configuration or user interaction. … 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 patches published in the Android Security Bulletin for September 1, 2026, available at https://source.android.com/docs/security/bulletin/2026/2026-09-01. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all Android devices in your environment and determine which are affected based on device model and current OS version; verify availability of the September 2026 Android Security Bulletin patch for each model. …
