CVE-2025-48615 in Android
Summary
by MITRE • 12/08/2025
In getComponentName of MediaButtonReceiverHolder.java, there is a possible desync in persistence due to resource exhaustion. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

The vulnerability identified as CVE-2025-48615 resides within the MediaButtonReceiverHolder.java component of an Android system, specifically targeting the getComponentName method implementation. This flaw represents a critical security weakness that stems from improper resource management during component name resolution processes. The vulnerability manifests when the system experiences resource exhaustion conditions that cause a desynchronization between expected and actual persistence states, creating a pathway for unauthorized privilege escalation.
The technical implementation flaw occurs when the MediaButtonReceiverHolder component fails to properly handle resource allocation during component name retrieval operations. This resource exhaustion scenario typically arises when the system's component name resolution mechanism encounters memory constraints or file descriptor limitations that prevent proper state synchronization. The vulnerability operates at the system level where component names are used to maintain persistent references to media button receivers, and when these resources become exhausted, the system's integrity mechanisms can be bypassed through state desynchronization.
From an operational perspective, this vulnerability presents a significant risk as it enables local privilege escalation without requiring any user interaction or additional execution privileges. The attack vector leverages the system's resource management weaknesses to manipulate component persistence states, allowing a malicious actor with local access to elevate their privileges to system level. This represents a particularly dangerous weakness because it can be exploited silently without detection, as no user interaction is required for the attack to succeed. The vulnerability's impact extends beyond simple privilege escalation to potentially enable full system compromise through subsequent exploitation vectors.
The underlying cause of this vulnerability aligns with CWE-404, which addresses improper resource management and resource exhaustion issues in software systems. This weakness creates conditions where the system's ability to maintain consistent state information becomes compromised, leading to the persistence desynchronization that enables privilege escalation. The vulnerability also relates to ATT&CK technique T1068, which involves the exploitation of system vulnerabilities for privilege escalation, and T1548.001, which covers abuse of system permissions. The resource exhaustion aspect of this vulnerability demonstrates how insufficient resource management can create security weaknesses that bypass traditional access control mechanisms.
Mitigation strategies for CVE-2025-48615 should focus on implementing robust resource management practices within the MediaButtonReceiverHolder component. System administrators should ensure that all component name resolution operations include proper resource cleanup mechanisms and that memory allocation limits are appropriately enforced. The implementation should incorporate resource monitoring and automatic cleanup procedures to prevent exhaustion conditions that could lead to state desynchronization. Additionally, the system should implement proper access controls and privilege separation mechanisms to limit the impact of any potential exploitation attempts. Regular system updates and patches should be applied immediately to address this vulnerability, as the resource exhaustion conditions can be triggered through normal system operations. The mitigation approach should also include monitoring for unusual resource consumption patterns that might indicate attempted exploitation of this vulnerability.
