{"id":"CVE-2026-46009","summary":"PCI: endpoint: pci-epf-ntb: Remove duplicate resource teardown","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nPCI: endpoint: pci-epf-ntb: Remove duplicate resource teardown\n\nepf_ntb_epc_destroy() duplicates the teardown that the caller is\nsupposed to do later. This leads to an oops when .allow_link fails or\nwhen .drop_link is performed. Remove the helper.\n\nAlso drop pci_epc_put(). EPC device refcounting is tied to configfs EPC\ngroup lifetime, and pci_epc_put() in the .drop_link path is sufficient.","modified":"2026-06-18T03:55:05.596636224Z","published":"2026-05-27T12:56:09.581Z","related":["openSUSE-SU-2026:10954-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46009.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3446beddba450c8d6f9aca2f028712ac527fead3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/65fc57c8b8f0b31be62be291cb1bb01755cec85d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/72099f015d3c77bf2eb703d1aab113bd7a60915a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/756ca5e7ed22d9045bb4de4c981f9149278d5cd3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c3029721b84f59e790285ad27544ed5d3cb0f2a6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c72f6a7ea638f95c486a5cfd86e567b646027687"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e813c95e4c8edd31599081e6356e20ada30e266d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46009.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46009"},{"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":"8b821cf761503b80d0bd052f932adfe1bc1a0088"},{"fixed":"c3029721b84f59e790285ad27544ed5d3cb0f2a6"},{"fixed":"c72f6a7ea638f95c486a5cfd86e567b646027687"},{"fixed":"72099f015d3c77bf2eb703d1aab113bd7a60915a"},{"fixed":"756ca5e7ed22d9045bb4de4c981f9149278d5cd3"},{"fixed":"65fc57c8b8f0b31be62be291cb1bb01755cec85d"},{"fixed":"e813c95e4c8edd31599081e6356e20ada30e266d"},{"fixed":"3446beddba450c8d6f9aca2f028712ac527fead3"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-46009.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.12.0"},{"fixed":"5.15.209"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.175"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.140"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.86"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.27"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-46009.json"}}],"schema_version":"1.7.5"}
