A vulnerability in the Linux kernel's software_node_get_reference_args() function allowed an out-of-bounds access due to improper bounds checking when the index UINT_MAX was passed. This issue has been resolved by fixing the bounds check to cover the UINT_MAX case.
AI Analysis
Technical Summary
The Linux kernel contained a vulnerability in the software_node_get_reference_args() function where the bounds check for the index parameter failed when the value UINT_MAX was passed. This failure led to an out-of-bounds access in the property array, potentially causing memory corruption or other impacts. The vulnerability has been fixed by correcting the bounds check to properly handle the UINT_MAX case.
Potential Impact
The vulnerability could lead to out-of-bounds memory access, which may result in confidentiality, integrity, and availability impacts as indicated by the CVSS vector (C:H/I:H/A:H). The attack vector is local with high attack complexity and requires low privileges without user interaction.
Mitigation Recommendations
A fix is available for this vulnerability as it has been resolved in the Linux kernel. Users should apply the official kernel updates that include the corrected bounds check in software_node_get_reference_args().
