Description OSIDB Bzimport 2025-10-01 12:08:46 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ALSA: aoa: i2sbus: fix possible memory leak in i2sbus_add_dev()

dev_set_name() in soundbus_add_one() allocates memory for name, it need be
freed when of_device_register() fails, call soundbus_dev_put() to give up
the reference that hold in device_initialize(), so that it can be freed in
kobject_cleanup() when the refcount hit to 0. And other resources are also
freed in i2sbus_release_dev(), so it can return 0 directly.
