U.S. Federal Agencies: CISA Warns of Android Framework Integer Overflow Vulnerability Exploited in Attacks

Critical Android Framework Vulnerability (CVE-2025-48595) Actively Exploited in the Wild

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added CVE-2025-48595, a newly disclosed Android Framework vulnerability, to its Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in real-world attacks. The flaw, classified as an integer overflow issue (CWE-190), stems from improper handling of integer values within Android’s core framework, leading to memory corruption and potential arbitrary code execution.

Exploitation of this vulnerability could enable local privilege escalation, allowing attackers to bypass security controls and gain elevated access to sensitive system resources. Due to its presence in a fundamental Android component, the flaw affects a broad range of devices and versions, amplifying its risk.

While CISA has not linked the vulnerability to ransomware campaigns, its inclusion in the KEV catalog underscores the urgency of remediation. Federal agencies are required to patch affected systems by June 5, 2026, under Binding Operational Directive (BOD) 22-01, though CISA advises all organizations and users to apply vendor patches immediately. If patches are unavailable, discontinuing use of vulnerable devices is recommended until fixes are deployed.

Security teams are advised to prioritize updates, enforce compliance policies, and monitor for signs of exploitation, particularly in enterprise mobility environments. The flaw highlights the persistent threat posed by vulnerabilities in Android’s core framework, which remains a prime target for attackers.
