A critical use-after-free vulnerability in Android 15 allows unauthenticated local attackers to achieve arbitrary code execution and escalate privileges.

The vulnerability is a use-after-free flaw that can be triggered in multiple locations within the system. An attacker with local access, requiring no additional privileges or user interaction, can leverage this defect to execute arbitrary code and gain elevated system privileges.

The ability for an unauthenticated local attacker to execute arbitrary code and escalate privileges represents a severe security risk. With a CVSS score of 8.4, this vulnerability could allow an attacker to bypass critical system protections, leading to total compromise of device integrity, confidentiality, and availability. Such a breach could result in unauthorized access to sensitive user data and long-term persistence on the affected hardware.

Immediate Action: Apply the security updates provided in the March 2025 Android Security Bulletin to all devices running Android 15.

Proactive Monitoring: Review system logs for unusual crashes or unauthorized attempts to access restricted system services that might indicate exploitation attempts.

Compensating Controls: Ensure that all installed applications are sourced from trusted app stores and maintain strict device access policies to mitigate the risk of local unauthorized access.

Public Exploit Available: Unknown

Given the high CVSS score and the potential for privilege escalation, administrators must prioritize the deployment of the March 2025 Android security patches. Ensuring that devices are running the latest patched version is the only effective way to neutralize the threat posed by this use-after-free vulnerability.
