{"id":"CVE-2026-93110","summary":"RDMA/core: Wait for RCU callbacks before unloading ib_core","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/core: Wait for RCU callbacks before unloading ib_core\n\nput_gid_ndev() is queued with call_rcu() and implemented in ib_core.\nStopping the workqueues does not drain callbacks already queued, so RCU\ncould invoke it after the module code has been unloaded.\n\nsynchronize_rcu() does not wait for callbacks. Wait for them after all\nproducers have stopped.","modified":"2026-09-19T03:47:31.533120573Z","published":"2026-09-17T16:11:19.805Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93110.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0d5817fa4819abdc445fa77b5be4f0d49334a864"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1646e123e56c3ad679fbfb571e8eef6386efb729"},{"type":"WEB","url":"https://git.kernel.org/stable/c/48b72fa0d209a92fb51b834a6080171cfa207b2c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7853af5f15738dc00aebaa1fc9f1f0df40f6f603"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7d75592114d1664623c8cf191a12b38052c04483"},{"type":"WEB","url":"https://git.kernel.org/stable/c/82dfd1df456227279b1c8c648983a530f2612098"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8e4f1677c09d75d738099f42afcf65d8587b664a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9d998297fdaf47492f6679287f6552879d1a7e3a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93110.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93110"},{"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":"943bd984b108b3bb778790c2da4ae8d186b547e6"},{"fixed":"82dfd1df456227279b1c8c648983a530f2612098"},{"fixed":"1646e123e56c3ad679fbfb571e8eef6386efb729"},{"fixed":"8e4f1677c09d75d738099f42afcf65d8587b664a"},{"fixed":"7853af5f15738dc00aebaa1fc9f1f0df40f6f603"},{"fixed":"0d5817fa4819abdc445fa77b5be4f0d49334a864"},{"fixed":"9d998297fdaf47492f6679287f6552879d1a7e3a"},{"fixed":"48b72fa0d209a92fb51b834a6080171cfa207b2c"},{"fixed":"7d75592114d1664623c8cf191a12b38052c04483"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93110.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.2.0"},{"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-2026-93110.json"}}],"schema_version":"1.9.0"}
