Linux kernel users and administrators should be aware of this vulnerability and take steps to ensure their systems are updated. This includes reviewing system configurations and dependencies, monitoring system logs for potential issues, and verifying the affected scope and severity with the official CVE record and vendor guidance.

Technical summary

The Linux kernel vulnerability CVE-2026-64161 was resolved in the net: ti: icssm-prueth driver. The vulnerability was caused by a potential eth_ports_node leak in the probe function. When of_property_read_u32() failed, the function returned without releasing the eth_ports_node, which was obtained before the for_each_child_of_node() loop. This issue can be addressed by updating the Linux kernel to the latest version.

Defensive priority

Medium

Recommended defensive actions

  • Update Linux kernel to the latest version
  • Verify system configurations and dependencies
  • Monitor system logs for potential issues
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
