{"id":"CVE-2026-31492","summary":"RDMA/irdma: Initialize free_qp completion before using it","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/irdma: Initialize free_qp completion before using it\n\nIn irdma_create_qp, if ib_copy_to_udata fails, it will call\nirdma_destroy_qp to clean up which will attempt to wait on\nthe free_qp completion, which is not initialized yet. Fix this\nby initializing the completion before the ib_copy_to_udata call.","modified":"2026-07-09T10:14:51.412190168Z","published":"2026-04-22T13:54:15.581Z","related":["SUSE-SU-2026:22433-1","SUSE-SU-2026:22436-1","SUSE-SU-2026:22458-1","SUSE-SU-2026:22460-1","SUSE-SU-2026:2722-1","SUSE-SU-2026:2799-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31492.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/11a95521fb93c91e2d4ef9d53dc80ef0a755549b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3cb88c12461b71c7d9c604aa2e6a9a477ecfa147"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ac1da7bd224d406b6f1b84414f0f652ab43b6bd8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/af310407f79d5816fc0ab3638e1588b6193316dd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cd1534c8f4984432382c240f6784408497f5bb0a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f72996834f7bdefc2b95e3eec30447ee195df44e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31492.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31492"},{"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":"b48c24c2d710cf34810c555dcef883a3d35a9c08"},{"fixed":"ac1da7bd224d406b6f1b84414f0f652ab43b6bd8"},{"fixed":"af310407f79d5816fc0ab3638e1588b6193316dd"},{"fixed":"cd1534c8f4984432382c240f6784408497f5bb0a"},{"fixed":"3cb88c12461b71c7d9c604aa2e6a9a477ecfa147"},{"fixed":"f72996834f7bdefc2b95e3eec30447ee195df44e"},{"fixed":"11a95521fb93c91e2d4ef9d53dc80ef0a755549b"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-31492.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.14.0"},{"fixed":"6.1.168"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.131"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.80"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.21"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.11"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-31492.json"}}],"schema_version":"1.7.5"}
