Description

In the Linux kernel, the following vulnerability has been resolved: net: ti: icssm-prueth: fix eth_ports_node leak in probe The error path on of_property_read_u32() failure inside icssm_prueth_probe() returns without putting eth_ports_node, which was acquired before the for_each_child_of_node() loop. Drop it before returning.

Attack-Flow Graph

Executive Summary

This vulnerability is a memory leak in the Linux kernel's TI ICSSM PRU Ethernet driver. During the probe function, the eth_ports_node is acquired but not properly released if a specific property read fails. This causes a resource leak when the driver fails to initialize correctly.

Detection Guidance

This vulnerability is specific to the Linux kernel's TI ICSSM PRU Ethernet driver. Detection requires checking if your kernel version includes the affected code path. Use uname -r to check your kernel version and grep for the driver in your kernel logs or source code.

Impact Analysis

The impact is limited to systems using the affected TI ICSSM PRU Ethernet driver. A memory leak could lead to gradual resource exhaustion, potentially causing system instability or performance degradation over time if the driver fails to initialize repeatedly.

Compliance Impact

This vulnerability does not directly affect compliance with standards like GDPR or HIPAA as it is a memory leak issue in the Linux kernel's network driver for TI ICSSM-PRUETH. It does not involve data exposure or unauthorized access that would typically impact such regulations.

Mitigation Strategies

Update your Linux kernel to a patched version that resolves this issue. Monitor your kernel logs for errors related to icssm_prueth_probe or eth_ports_node leaks after applying the update.
