Technical description
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.
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.

How can CyberStrike help with CVE-2026-80625?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-80625 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
