What is CVE-2026-93152?
CVE-2026-93152 is a vulnerability in Linux, published on 17 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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.
