In createSessionInternal of PackageInstallerService.java, there is a possible way to permanently DoS the device due to a logic error in the code. This could lead to local denial of service with no additional execution privileges needed. User interaction is not needed for exploitation.
AnalysisAI
Permanent local denial-of-service in Android's PackageInstallerService allows a low-privilege local attacker to irreversibly disable an affected device through a logic error in the createSessionInternal session-creation path. Affected releases are Android 16-qpr2 and Android 17, as confirmed by Google's September 2026 Android Security Bulletin. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires local code execution with at least low-privilege access - meaning an attacker must have an application already running on the target Android device (AV:L, PR:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 5.5 (Medium) captures the local-only vector and low-privilege requirement, but the high availability impact (A:H) is qualitatively significant because the DoS is permanent - a single exploitation event disables the device until an OEM recovery procedure is performed, which raises practical impact above what a typical 5.5 score implies. … 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, which addresses this issue with the 2026-09-01 security patch level. … Detailed patch versions, workarounds, and compensating controls in full report. |
