cve 2025 37977

CVE-2025-37977 is a Linux kernel vulnerability affecting the Exynos UFS host driver. It arises when the device tree lacks the dma-coherent property, causing descriptors to be treated as non-cacheable while IOC shareability bits remain enabled. This incompatible configuration can lead to random cache-related stability issues and system hangs. The bug is a configuration/compatibility flaw rather than a privilege-escalation exploit, but it impacts system availability on affected kernels. Discussions on WindowsForum.com cover the technical details, affected hardware, and the patch that resolves the issue. Users interested in Linux kernel security, Exynos chipsets, or UFS storage stability will find relevant analysis and community insights under this tag.
