Detailsinfo

A vulnerability was found in Linux Kernel up to 6.15.3. It has been rated as problematic. Affected by this issue is the function software_node_get_reference_args. The manipulation with an unknown input leads to a out-of-bounds vulnerability. Using CWE to declare the problem leads to CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. Impacted is confidentiality. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: software node: Correct a OOB check in software_node_get_reference_args() software_node_get_reference_args() wants to get @index-th element, so the property value requires at least '(index + 1) * sizeof(*ref)' bytes but that can not be guaranteed by current OOB check, and may cause OOB for malformed property. Fix by using as OOB check '((index + 1) * sizeof(*ref) > prop->length)'.

The advisory is shared for download at git.kernel.org. This vulnerability is handled as CVE-2025-38342 since 04/16/2025. There are known technical details, but no exploit is available.
