If the userspace access fails, uverbs preserves the\nuobject and allows the destroy callback to run again, even though the\ndriver resource has already been freed.\n\nCall ib_no_udata_io() before teardown so udata failures are detected\nwhile the resource is still intact, then return success after teardown\ncompletes.\n\nAs part of this change, move ib_respond_empty_udata() to the start of\nthe create and modify flows. While this is not strictly required for\ngeneral create flows, as the core layer unwinds uobjects on failure, it\nis necessary for create AH. In _rdma_create_ah(), the HW object is\notherwise leaked.","state":0,"publishedAt":"2026-09-24T15:52:19.49+00:00","modifiedAt":"2026-10-19T09:08:31.636+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/infiniband/hw/bnxt_re/ib_verbs.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"bed686d8dcd4fbcaa18cf67468caaf8772acfc7a\",\n                            \"lessThan\": \"c5643ea4f040acc2f4d1e88f49bd0be51110ff2f\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"bed686d8dcd4fbcaa18cf67468caaf8772acfc7a\",\n                            \"lessThan\": \"d38c835925d4a3bfdf0a85ff2829ee90c709c561\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/infiniband/hw/bnxt_re/ib_verbs.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"7.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"7.1\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.6\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/c5643ea4f040acc2f4d1e88f49bd0be51110ff2f","https://git.kernel.org/stable/c/d38c835925d4a3bfdf0a85ff2829ee90c709c561"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-93277","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-93277","identifiers":["CVE-2026-93277"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
