CVE-2025-48542

Permanent service interruption via unbounded account-data writes

Published Sep 4, 2025 · Updated Sep 4, 2025

Resource exhaustion in Android 13 through 16 AccountManagerService allows local users to cause a permanent service interruption. Multiple account-data write paths accept oversized values without per-account storage limits, allowing the AccountManager database to consume excessive storage. Low-privileged local execution is sufficient and requires no user interaction; the resulting exhaustion can leave the account service permanently unavailable.
