CVE-2025-20904

Memory corruption via missing trustlet input validation

Published Feb 4, 2025 · Updated Feb 4, 2025

Out-of-bounds write in Samsung Mobile Devices before SMR Feb-2025 Release 1 allows local privileged attackers to corrupt memory. The mPOS TUI trustlet fails to validate an unspecified input before writing, permitting a write beyond the intended memory boundary. Exploitation requires privileged local access to an Android 12, 13, or 14 device with a Qualcomm chipset; no more specific consequence than memory corruption is disclosed.
