Google’s November 2025 Android update includes fixes for two vulnerabilities in the core System component, most notably addressing a critical remote code execution (RCE) flaw.
Critical Remote Code Execution Fix
The security updates are included in the 2025-11-01 security patch level, the only patch level released this month by the company.
Google’s bulletin stated that the most severe vulnerability could allow for remote code execution with no additional execution privileges needed. Crucially, user interaction is not required for an attacker to exploit this severe issue.
The two fixed vulnerabilities are:
- CVE-2025-48593: This insufficient validation of user input could lead directly to remote code execution (RCE). The flaw impacts Android versions 13, 14, 15, and 16.
- CVE-2025-48581: A logic error in the VerifyNoOverlapInSessions function could be abused to block security updates through mainline installations. This could lead to a local escalation of privilege without needing additional execution rights. This flaw impacts only Android version 16.
Google confirmed it is not aware of any attacks in the wild actively exploiting these two vulnerabilities.
