CVE-2025-39872

CVE-2025-39872 concerns the Linux kernel function hsr_get_port_ndev. The issue arises because hsr_get_port_ndev calls hsr_for_each_port and requires both the RCU lock and a device reference, but returning the port device without proper synchronization could yield use-after-free in the caller. The...
