A command timeout clears ERDMA_CMDQ_STATE_OK_BIT and\npermanently disables the command queue, so no retry can succeed; the RDMA\ncore keeps the object after a failed destructor and forced uverbs cleanup\nthen nulls the pointers, making the resources unreachable.\n\nWarn on failure but release every software-owned resource and return\nsuccess, since during terminal destruction the hardware command result is\nonly diagnostic.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.0},"cwes":[],"references":["https://git.kernel.org/stable/c/334145d683ad3e31d052247f10807f2ebc950351","https://git.kernel.org/stable/c/3886d944b506e0cc681646beb03c3024cb375a68","https://git.kernel.org/stable/c/5fcfc988ecf3e2bbe308b95c2c0d2f011d9afabe","https://git.kernel.org/stable/c/652befcba956ef357f480525ccbe25c59bc81d4d","https://git.kernel.org/stable/c/ce7d205c264665517c25e8a3231cf2d0c2443e3c"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-92488","score":0.00155,"percentile":0.04572,"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).
