# CVE-2026-93046

> 7.0 HIGH

## Beschreibung

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.
