CVE-2025-54601

Memory corruption via concurrent ioctl race

Published Apr 6, 2026 · Updated Apr 6, 2026

Double free in the Samsung Exynos Wi-Fi driver allows local users to corrupt memory by racing ioctl calls across multiple threads. The driver accesses a global variable without adequate synchronization, allowing concurrent ioctl paths to free the same allocation. Low privileges and a locally running multithreaded process are required; the public record does not specify whether exploitation causes a crash or code execution.
