Overview

What is CVE-2026-80625?

In the Linux kernel, the following vulnerability has been resolved:

RDMA/hns: Fix memory leak of bonding resources

In a corner case of concurrent driver removal and driver reset, bonding resource is first released in hns_roce_hw_v2_exit() during driver removal, and then is allocated again in hns_roce_register_device() during driver reset. This leads to memory leak because the release timing has already passed.

This may also lead to a kernel panic as below because of the leaked notifier callback:

Call trace: 0xffffa20fccc04978 (P) raw_notifier_call_chain+0x20/0x38 call_netdevice_notifiers_info+0x60/0xb8 netdev_lower_state_changed+0x4c/0xb8

As Sashiko suggested, the teardown order of bonding resources should be inverted to make sure the resources are released when the driver is removed.
