Detailsinfo

A vulnerability was found in Linux Kernel up to 6.1.187/6.6.156/6.12.109/6.18.51/7.2.5 and classified as very critical. This issue affects the function apple_nvme_init_queue of the component nvme-apple. The manipulation with an unknown input leads to a race condition vulnerability. Using CWE to declare the problem leads to CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.

It is possible to read the advisory at git.kernel.org. The identification of this vulnerability is CVE-2026-93152 since 09/17/2026. The exploitation is known to be easy. Attacking locally is a requirement. The exploitation requires an enhanced level of successful authentication. Technical details of the vulnerability are known, but there is no available exploit. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 09/17/2026).

Upgrading to version 6.1.188, 6.6.157, 6.12.110, 6.18.52, 7.2.6 or 7.3-rc1 eliminates this vulnerability. Applying the patch cbe53ecd696e354bfda8173364f7595759bc562d/86782a72c6d8c7541813b9ddb009668468601f18/0e9d9fe12da779516dc3899dc9141304675f5416/e5a79244a3c526a76d930f2ef30aff64528b0c6a/840ab22ffa4d859ca40a31e96fc3554688e7a035/f61c934aa084b7440fec681be3f4b481eb5a8609 is able to eliminate this problem.
