CVE-2026-90233

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.
