Description
In the Linux kernel, the following vulnerability has been resolved:
nvme-apple: Use acquire/release for queue enabled state
apple_nvme_init_queue() initializes queue state and then marks the queue enabled. The interrupt and request paths check enabled before using that queue state.
The old wmb() after WRITE_ONCE(enabled, true) does not publish the earlier initialization before enabled becomes visible. Use a release store when enabling the queue and acquire loads when testing it.
Although the shutdown-side enabled accesses are not used for publishing queue initialization, use helpers for them as well for consistency.
