Summary
In 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().
unreferenced object 0xffff00c01aba2100 (size 128):
comm "systemd-udevd", pid 1259, jiffies 4294903284 (age 294.152s)
hex dump (first 32 bytes):
