Technical description
In the Linux kernel, the following vulnerability has been resolved:
nvme-pci: release descriptor pools on probe failure
The per-NUMA-node descriptor DMA pools are created lazily from
nvme_init_hctx_common() once the admin tag set is allocated, but they are
only destroyed in nvme_remove() via nvme_release_descriptor_pools(). Any
probe failure after the admin tag set has been allocated unwinds through
the out_disable label and nvme_pci_free_ctrl(), neither of which releases
the pools, leaking the dma_pool objects.
Release the descriptor pools in the out_disable error path. It must not
be added to nvme_pci_free_ctrl(), as that would double-free against
nvme_remove() on the normal teardown path.
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.

How can CyberStrike help with CVE-2026-90233?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-90233 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
