CVE-2025-48631Network attack vector

Persistent crash loop via oversized image decoding

Published Dec 8, 2025 · Updated Mar 6, 2026

Resource exhaustion in Android 14, 15, 16, and 16-qpr2 allows remote authenticated users to cause a persistent device crash loop. LocalImageResolver.onHeaderDecoded accepts oversized image dimensions without a hard decoding limit, allowing notification image decoding to consume device memory. No user interaction is required, but low-privileged access is reflected in the published CVSS assessments; the bounded impact is persistent service interruption through repeated crashes.
