Summary
CVE-2024-31317 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Google Android. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 47% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-31317 is an unsafe deserialization vulnerability present in multiple functions of ZygoteProcess.java within the Android frameworks/base component. The flaw permits code execution in the context of any app when an attacker possesses the WRITE_SECURE_SETTINGS permission, and it is tracked under CWE-502. The issue received a CVSS 3.1 base score of 7.8 reflecting local attack vector, low complexity, and high impact on confidentiality, integrity, and availability.
An attacker with existing user-level execution privileges on an affected Android device can exploit the vulnerability without user interaction to escalate privileges and run arbitrary code as any installed application. Because the flaw resides in core system code handling secure settings, the escalation occurs entirely through local means after the required permission is obtained.
The June 2024 Android security bulletin and the associated framework patch at android.googlesource.com address the issue by correcting the deserialization paths in ZygoteProcess.java. The EPSS score has remained modest, with a recorded peak of 0.0796 and a current value of 0.0703, indicating limited observed exploitation interest to date.

Vulnerability Data
In multiple functions of ZygoteProcess.java, there is a possible way to achieve code execution as any app via WRITE_SECURE_SETTINGS due to unsafe deserialization. This could lead to local escalation of privilege with User execution privileges needed. User interaction is not…

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can uncover deserialization flaws before deployment.
Input validation directly stops deserialization of untrusted data by ensuring inputs are valid before processing.
Engineering principles such as safe deserialization and input sanitization structurally prevent the weakness from being introduced.
Integrity verification tools can detect malformed or tampered serialized data after the fact.

PR.PS-02 addresses only post-deployment updates/patching and cannot prevent introduction of unsafe deserialization code, yet it can remediate some instances when the flaw exists in outdated libraries or components.

Security testing includes validation of deserialization routines and the use of untrusted data, reducing the likelihood that unsafe object reconstruction will be deployed.
Requiring vetted libraries, regular updates and SAST before release reduces the likelihood that deserialization logic will accept and act on attacker-controlled serialized objects.
Regular scanning of third-party libraries and timely patching reduce the likelihood that unsafe deserialization vulnerabilities remain active.
