Description OSIDB Bzimport 2024-08-26 11:21:44 UTC 
In the Linux kernel, the following vulnerability has been resolved:

nvme: apple: fix device reference counting

Drivers must call nvme_uninit_ctrl after a successful nvme_init_ctrl.
Split the allocation side out to make the error handling boundary easier
to navigate. The apple driver had been doing this wrong, leaking the
controller device memory on a tagset failure.
