Vulnerability from github – Published: 2025-09-16 18:31 – Updated: 2025-12-02 00:31In the Linux kernel, the following vulnerability has been resolved:
net: hns: fix possible memory leak in hnae_ae_register()
Inject fault while probing module, if device_register() fails, but the refcount of kobject is not decreased to 0, the name allocated in dev_set_name() is leaked. Fix this by calling put_device(), so that name can be freed in callback function kobject_cleanup().
