Any\nprobe failure after the admin tag set has been allocated unwinds through\nthe out_disable label and nvme_pci_free_ctrl(), neither of which releases\nthe pools, leaking the dma_pool objects.\n\nRelease the descriptor pools in the out_disable error path. It must not\nbe added to nvme_pci_free_ctrl(), as that would double-free against\nnvme_remove() on the normal teardown path.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
