CVE-2025-68316

Kernel oops via accepted UFS probe failure

Published Dec 16, 2025 · Updated Dec 16, 2025

Incorrect error handling in Linux 6.13 through 6.17.7 allows attackers to trigger a kernel oops when a failed UFS driver is removed. After DME Link Startup fails, ufshcd_init() passes the positive MIPI UniPro failure code 1 to probe callers that interpret only negative values as errors. The failure requires a UFS host-controller probe error followed by driver removal, leaving the driver invalid and interrupting the affected system.
