Detailsinfo

A vulnerability was found in Linux Kernel up to 6.17.7. It has been classified as critical. Affected is the function ufshcd_init. The manipulation with an unknown input leads to a return value vulnerability. CWE is classifying the issue as CWE-252. The product does not check the return value from a method or function, which can prevent it from detecting unexpected states and conditions. The impact remains unknown. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: scsi: ufs: core: Fix invalid probe error return value After DME Link Startup, the error return value is set to the MIPI UniPro GenericErrorCode which can be 0 (SUCCESS) or 1 (FAILURE). Upon failure during driver probe, the error code 1 is propagated back to the driver probe function which must return a negative value to indicate an error, but 1 is not negative, so the probe is considered to be successful even though it failed. Subsequently, removing the driver results in an oops because it is not in a valid state. This happens because none of the callers of ufshcd_init() expect a non-negative error code. Fix the return value and documentation to match actual usage.

The advisory is available at git.kernel.org. This vulnerability is traded as CVE-2025-68316 since 12/16/2025. Technical details are known, but there is no available exploit.
