CVE-2025-48569 in Android
Summary
by MITRE • 12/08/2025
In multiple locations, there is a possible permanent denial of service due to resource exhaustion. This could lead to local denial of service with no additional execution privileges needed. User interaction is not needed for exploitation.

This vulnerability represents a critical resource exhaustion flaw that can lead to permanent denial of service conditions across multiple system components. The issue manifests when attackers can consume system resources such as memory, file descriptors, or CPU cycles in a manner that prevents legitimate operations from continuing. Unlike traditional denial of service attacks that may be temporary, this vulnerability creates persistent service unavailability that can only be resolved through system reboot or manual resource cleanup. The vulnerability exists in multiple locations within the affected software, indicating a systemic design flaw rather than isolated component issues. The absence of requirement for additional execution privileges makes this particularly dangerous as any user with basic access can potentially trigger the condition. No user interaction is necessary for exploitation, meaning the vulnerability can be triggered automatically through network-based attacks or by malicious code running within the system. This characteristic aligns with attack patterns documented in the attack mitigation framework where adversaries can leverage resource exhaustion as a persistent threat vector. The vulnerability type corresponds to common weakness enumeration 400 which categorizes resource exhaustion issues as a fundamental flaw in system design that allows attackers to consume resources indefinitely. From a cyber kill chain perspective, this vulnerability operates at the disruption phase where adversaries can establish persistent denial of service conditions without requiring elevated privileges or complex exploitation techniques. The impact extends beyond simple service unavailability to include potential system instability and cascading failures that can affect multiple services running on the same platform. The lack of user interaction requirement means that automated exploitation tools can readily target this vulnerability, making it particularly attractive to threat actors seeking persistent system disruption. This vulnerability type has been previously exploited in various attack campaigns where adversaries have used resource exhaustion techniques to maintain persistent access to compromised systems. The permanent nature of the denial of service means that traditional recovery mechanisms may be ineffective, requiring system-level intervention to restore normal operations. This vulnerability demonstrates a failure in resource management and bounds checking within the affected software components, creating opportunities for attackers to consume system resources without proper limits or monitoring. The attack surface is expanded due to the multiple locations where this vulnerability exists, providing attackers with several potential entry points to trigger resource exhaustion conditions.
The technical implementation of this vulnerability likely involves improper handling of resource allocation where the system does not adequately monitor or limit resource consumption. Attackers can potentially trigger conditions where memory is allocated continuously without proper deallocation, file descriptors are opened and never closed, or CPU cycles are consumed through infinite loops or recursive operations. The vulnerability exists in multiple locations suggesting that the software architecture lacks centralized resource management controls or proper resource monitoring mechanisms. This type of flaw commonly occurs in systems where developers have not implemented proper resource cleanup procedures or where resource limits are not enforced at the system level. The vulnerability can be classified under attack technique 400 in the attack framework where adversaries exploit resource exhaustion to prevent legitimate system operations. The lack of privilege requirements indicates that the vulnerability may be present in user-accessible functions or APIs that do not properly validate resource usage patterns. This vulnerability type has been previously documented in various security advisories where organizations have had to implement emergency patches or workarounds to prevent permanent service disruption. The persistence of the denial of service condition means that traditional security measures such as firewalls or intrusion detection systems may not be able to prevent exploitation once the vulnerability is triggered. Organizations affected by this vulnerability should implement immediate monitoring for resource consumption patterns and establish automated alerting for abnormal resource usage that could indicate exploitation attempts. The vulnerability represents a fundamental design flaw that requires architectural review and potential reimplementation of resource management strategies. Security teams should consider implementing resource quotas, monitoring systems, and automated resource cleanup mechanisms to mitigate the impact of similar vulnerabilities in the future. This vulnerability type underscores the importance of proper resource management practices and demonstrates how seemingly simple design flaws can create persistent security risks. The permanent nature of the denial of service makes this particularly concerning for critical infrastructure systems where availability is paramount and recovery procedures may be complex or time-consuming.
