{"id":"CVE-2026-93109","summary":"RDMA/mlx5: Drain RCU callbacks during module teardown","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/mlx5: Drain RCU callbacks during module teardown\n\ndevx_free_subscription() can remain queued after the last DevX event file\ndrops its module reference or an auxiliary driver detaches its devices.\nmlx5_ib can then unload before the callback runs.\n\nRegistration error unwind has the same risk because driver registration\ncan attach existing devices before failing. Wait after all drivers have\nstopped.","modified":"2026-09-19T03:47:31.535432234Z","published":"2026-09-17T16:11:19.135Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93109.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2f946e7839f677fa14574b6babad14b37ae0bbbe"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4664368b9bd9d5d79ebad24056b98c34b9fed20f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4be7810ba70291abb2f68cc6db0ae1b93ee9c76a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/59d60e04afd012f07e996d2e34cb90a4ec6f5cff"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7babc25d8dd5b7642920fbc0737cfd1469e7025b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ca428e597f12b278bf158356e34641e6386cfa82"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e37cdd75f8d61c1123d324ae5667ac3da562290e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93109.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93109"},{"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":"6898d1c661d79f4707d8ba82991b2195822780ca"},{"fixed":"ca428e597f12b278bf158356e34641e6386cfa82"},{"fixed":"59d60e04afd012f07e996d2e34cb90a4ec6f5cff"},{"fixed":"2f946e7839f677fa14574b6babad14b37ae0bbbe"},{"fixed":"4be7810ba70291abb2f68cc6db0ae1b93ee9c76a"},{"fixed":"7babc25d8dd5b7642920fbc0737cfd1469e7025b"},{"fixed":"4664368b9bd9d5d79ebad24056b98c34b9fed20f"},{"fixed":"e37cdd75f8d61c1123d324ae5667ac3da562290e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93109.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.6.0"},{"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-2026-93109.json"}}],"schema_version":"1.9.0"}
