Assigner: Linux
Reserved: 17.09.2026 Published: 17.09.2026 Updated: 17.09.2026

In the Linux kernel, the following vulnerability has been resolved:

software node: Fix software_node_get_reference_args() with index -1

The bounds check for the index passed to software_node_get_reference_args() was failing when passed UINT_MAX, this in turn would lead to an out of bound access in the property array. Fix the bound check to also cover the UINT_MAX case.
