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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":[],"references":["https://git.kernel.org/stable/c/c5643ea4f040acc2f4d1e88f49bd0be51110ff2f","https://git.kernel.org/stable/c/d38c835925d4a3bfdf0a85ff2829ee90c709c561"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-93277","score":0.00143,"percentile":0.03613,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
