{"id":"CVE-2026-90233","summary":"nvme-pci: release descriptor pools on probe failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnvme-pci: release descriptor pools on probe failure\n\nThe per-NUMA-node descriptor DMA pools are created lazily from\nnvme_init_hctx_common() once the admin tag set is allocated, but they are\nonly destroyed in nvme_remove() via nvme_release_descriptor_pools(). 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.","modified":"2026-09-19T03:47:25.484322996Z","published":"2026-09-17T16:07:39.941Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90233.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/79fb405966edb5065234440d94cc75bfd7b01f41"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c25b6b28a35f9e36ce5dd6da5905bcddb2128707"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cb144c2f67128abfa5c7ba33318617d19f192156"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90233.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90233"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"d977506f8863807129d7a11f4057dfb1b38085ea"},{"fixed":"c25b6b28a35f9e36ce5dd6da5905bcddb2128707"},{"fixed":"79fb405966edb5065234440d94cc75bfd7b01f41"},{"fixed":"cb144c2f67128abfa5c7ba33318617d19f192156"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90233.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.16.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90233.json"}}],"schema_version":"1.9.0"}
