{"id":"CVE-2026-93108","summary":"RDMA/ipoib: Drain RCU callbacks during module teardown","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/ipoib: Drain RCU callbacks during module teardown\n\nIPoIB reclamation completions can be signaled from inside an RCU callback.\nTeardown can wake before the callback returns and unload ib_ipoib while its\ncode is still executing.\n\nClient registration failure can also remove already-added devices and queue\ncallbacks. Wait after client and workqueue teardown.","modified":"2026-09-19T03:47:27.930139823Z","published":"2026-09-17T16:11:18.455Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93108.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/24ce944721dcd92ae62e7a448d770e2a3e79f5fd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2b3330cfc097db2d31f47ad09261967630270d66"},{"type":"WEB","url":"https://git.kernel.org/stable/c/31b7c700670830a0e8a4cdcd451c88a13cc5dc48"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4a6dc313f9661f80e4ed43461d7ed5615c2450ca"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7bc08d7f9338c9f9c09965e5d020591c793a80cb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8dc5ffcb8efcc01e44dd1ebc490eaae72de3fadf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bb9c23733a0c50e136bd40c27cb60023cc58e22c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d8917353966d1d5a486437dd0dd68a2cf8ecb136"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93108.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93108"},{"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":"b63b70d8774175b6f8393c495fe455f0fba55ce1"},{"fixed":"bb9c23733a0c50e136bd40c27cb60023cc58e22c"},{"fixed":"4a6dc313f9661f80e4ed43461d7ed5615c2450ca"},{"fixed":"d8917353966d1d5a486437dd0dd68a2cf8ecb136"},{"fixed":"7bc08d7f9338c9f9c09965e5d020591c793a80cb"},{"fixed":"2b3330cfc097db2d31f47ad09261967630270d66"},{"fixed":"8dc5ffcb8efcc01e44dd1ebc490eaae72de3fadf"},{"fixed":"24ce944721dcd92ae62e7a448d770e2a3e79f5fd"},{"fixed":"31b7c700670830a0e8a4cdcd451c88a13cc5dc48"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93108.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.6.0"},{"fixed":"5.10.270"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.221"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"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-2026-93108.json"}}],"schema_version":"1.9.0"}
