Linux Kernel UFS Vulnerability in Exynos Devices

CVE-2025-37977

What is CVE-2025-37977?

A configuration vulnerability has been identified in the Linux kernel affecting UFS functionality within Exynos devices. When the dma-coherent property is not set, descriptors within the configuration may become non-cacheable, leading to potential mismatches that disable iocc shareability bits. This misconfiguration can result in unstable operation of the UFS, causing random cache-related issues that jeopardize system stability and performance. It is crucial for users and developers to ensure that the dma-coherent property is correctly configured to avoid these complications.
