CVE-2025-52512Network attack vector

Denial of service via HTS driver race

Published Nov 4, 2025 · Updated Nov 4, 2025

Out-of-bounds read in the HTS driver for Samsung Exynos 2400, 1580, and 2500 allows remote attackers to interrupt service. A race in the HTS driver permits an out-of-bounds memory read; Samsung has not disclosed the competing operations or affected function. Network access without authentication or user interaction is sufficient; Samsung identifies denial of service but does not specify whether the device hangs, crashes, or reboots.
