CVE-2025-48633 is an information disclosure vulnerability in Android Framework. CISA added it to the Known Exploited Vulnerabilities catalogue on 2 December 2025, which means attackers have used it in real attacks. Android Framework contains an unspecified vulnerability that allows for information disclosure.
What this vulnerability means in Android Framework
information disclosure vulnerabilities matter because they let an attacker obtain data the platform did not intend to expose. In a core system component like Android Framework, that can widen the visibility of data flowing through the operating system, including information that may help an attacker plan later compromise or bypass defensive assumptions.
For a CVE page, the key point is not only that the flaw exists, but that it was important enough for CISA to place it in the Known Exploited Vulnerabilities catalogue. That elevates the issue from a theoretical weakness to one that has been observed in real-world attack activity.
Why information disclosure in a framework layer is dangerous
Framework-level disclosure issues are especially sensitive because they sit close to the operating system’s shared services and data-handling pathways. A weakness here can expose information across app, device, or user boundaries, depending on the exact flaw and how the platform component processes requests.
Even when the vulnerability does not directly grant code execution, exposed information can still be operationally serious. Leaked data may include identifiers, internal state, tokens, file contents, or other material that supports follow-on exploitation, targeted phishing, session abuse, or privilege escalation chains.
Android Framework sits in the trust path for many device functions, so an information leak in this layer should be treated as a platform exposure rather than a narrow application bug. The practical concern is often not just the data disclosed, but what that disclosure enables next.
How organisations check exposure and scope
Exposure review starts with knowing which Android devices, builds, and management profiles exist in the estate, then matching them against vendor advisories and the official CISA KEV entry. That is the reliable way to determine whether the organisation has reachable devices that may be at risk, rather than guessing from the CVE name alone.
Teams should also assess whether affected devices are internet-reachable, enrolled in mobile device management, used for sensitive business access, or tied to privileged workflows. A disclosure flaw on a lightly used test device is not the same as the same flaw on a managed fleet used for email, authentication, or internal app access.
For prioritisation, NIST National Vulnerability Database and the CVE Program provide the canonical record structure, while the vendor advisory gives the version and remediation details you should use operationally.
Remediation, detection, and identity impact
If patching cannot happen immediately, organisations should reduce exposure by limiting high-risk device use, tightening access to sensitive apps and data on those devices, and increasing monitoring for unusual data access patterns. This is a compensating-control problem as much as a patching problem.
Detection should focus on signs that the disclosure has been used as part of a broader compromise, such as abnormal application behavior, unexpected access to data that would normally be hidden, or post-exploitation activity that suggests the attacker used leaked information to move further. After patching, review whether the device or associated accounts were already touched before the fix was applied.
If exploitation exposed credentials, sessions, API tokens, or other secret material stored or accessible on the device, rotate the relevant secrets and revoke active sessions where possible. For patch sequencing and remediation discipline, Vulnerability Management Guide is a useful companion, and post-compromise review should align with the broader lessons in The State of NHI & AI Agent Breach Report 2026 where exposed secrets and compromised identities drive the next stage of attack.
Risk and Threat Considerations
An information disclosure flaw in a widely deployed mobile framework creates risk even when the immediate bug looks limited. Attackers value these issues because leaked data can reveal system state, user context, or trust material that helps them select a better follow-on exploit or bypass normal defenses.
Failure mechanism: The vulnerable framework path returns data that should have remained hidden, and that disclosure may be repeated at scale across many devices before defenders notice.
Impact: Exposure can support lateral abuse, targeted exploitation, credential or session theft, and deeper compromise of devices that hold sensitive business access.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST SP 800-53 Rev 5 and CIS Controls v8 set the technical controls, while ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-53 Rev 5 | SI-2 — Flaw Remediation | CVE exposure and patch prioritisation map to remediation of known flaws. |
| SI-4 — System Monitoring | Disclosure flaws need detection for abnormal access and post-compromise activity. | |
| RA-5 — Vulnerability Monitoring and Scanning | KEV-listed CVEs require inventory, exposure review, and prioritised scanning. | |
| Recommendation — Track Android Framework remediation status and apply verified fixes quickly. Monitor affected devices for suspicious data access and exploitation signals. Scan device inventories against the CVE and prioritise exposed Android assets. | ||
| ISO/IEC 27001:2022 | A.8.8 — Management of technical vulnerabilities | This CVE requires vulnerability identification, prioritisation, and remediation governance. |
| Recommendation — Manage the Android vulnerability through documented triage and remediation. | ||
| CIS Controls v8 | CIS-7 — Continuous Vulnerability Management | KEV-backed exploitation makes continuous exposure tracking materially important. |
| Recommendation — Continuously inventory, assess, and remediate exposed Android devices. | ||
Practitioner Guidance
Why practitioners should care: Treat KEV-listed mobile framework flaws as fleet exposure items, not routine patch notes. The practical question is whether the vulnerable code can still be reached in the devices that matter most to the business.
What to watch for: Prioritise devices with sensitive apps, privileged access, or external connectivity, then confirm patch status against vendor guidance and the CISA catalogue. If the flaw may have been exploited, assume the issue may extend beyond disclosure and review accounts, sessions, and stored secrets tied to those devices.
