Overview
What is CVE-2024-43913?
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.
