CISA warned today that two Android zero-day vulnerabilities are under active attack, within hours of Google releasing patches for the flaws. Both are high-severity Android framework vulnerabilities. CVE-2025-48572 is a Privilege Escalation vulnerability, while CVE-2025-48633 is an Information Disclosure vulnerability. Both were among 107 Android vulnerabilities addressed by Google in its December security bulletin released today.

Android Vulnerabilities CVE-2025-48572 and CVE-2025-48633 Under Attack

Google warned that the CVE-2025-48572 and CVE-2025-48633 framework vulnerabilities “may be under limited, targeted exploitation.” The U.S. Cybersecurity and Infrastructure Security Agency (CISA) followed with its own alert adding the Android vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog. “These types of vulnerabilities are a frequent attack vector for malicious cyber actors and pose significant risks to the federal enterprise,” CISA warned. “CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of KEV Catalog vulnerabilities as part of their vulnerability management practice,” the U.S. cybersecurity agency added. The vulnerabilities are so new that the CVE Program lists the CVE numbers as “reserved,” with details yet to be released. Neither Google nor CISA provided further details on how the vulnerabilities are being exploited.

7 Critical Android Vulnerabilities Also Patched

The December Android security bulletin also addressed seven critical vulnerabilities, the most severe of which is CVE-2025-48631, a framework Denial of Service (DoS) vulnerability that Google warned “could lead to remote denial of service with no additional execution privileges needed.” Four of the critical vulnerabilities affect the Android kernel and are all Elevation of Privilege (EoP) vulnerabilities: CVE-2025-48623, CVE-2025-48624, CVE-2025-48637, and CVE-2025-48638. The other two critical vulnerabilities affect Qualcomm closed-source components: CVE-2025-47319, an Exposure of Sensitive System Information to an Unauthorized Control Sphere vulnerability, and CVE-2025-47372, a Buffer Overflow vulnerability that could lead to memory corruption. Google lists CVE-2025-47319 as “Critical” while Qualcomm lists the vulnerability as Medium severity; both list CVE-2025-47372 as Critical. The Qualcomm vulnerabilities are addressed in detail in The Cyber Express article Qualcomm Issues Critical Security Alert Over Secure Boot Vulnerability published earlier today.
