CVE-2026-20968

Local privileged code execution via freed object reuse

Published Jan 9, 2026 · Updated Jan 9, 2026

Use-after-free in DualDAR on Samsung Mobile Devices running Android 13 through 16 allows local privileged attackers to execute arbitrary code. Samsung identifies the affected locus only as DualDAR and has not disclosed which object is freed prematurely or which later operation reuses it. Exploitation requires existing high local privileges and no user interaction, and successful abuse executes attacker-controlled code on the device.
