The init_conns() and stop-and-destroy paths then call\ndestroy_con_cq_qp() while cq is still NULL (no PUT) and only afterwards\nrdma_destroy_id().\n\nCMA serializes the handler against rdma_destroy_id() with handler_mutex,\nbut that does not order the GET against destroy_con_cq_qp(). If\nADDR_RESOLVED has already passed the DESTROYING check, it can take\ncon_mutex, GET credits, and then lose the con to kfree. Device\nunregister later hits WARN_ON(cq->cqe_used) in ib_cq_pool_cleanup().\n\nSet a per-connection flag under con_mutex before CQ/QP teardown so a\nracing ADDR_RESOLVED cannot borrow credits after teardown has begun.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/2ae16aaa78b5edc6e6d0904c84fd9cdfb762bcda","https://git.kernel.org/stable/c/31024e158b45358370a0a14ed96589e6aa62d6cb","https://git.kernel.org/stable/c/6f8020fe7465f49e234a576c04e415e9d08c7878","https://git.kernel.org/stable/c/74c4ed55e61f1b65ddbebc5b635d136461a1c3da","https://git.kernel.org/stable/c/8f253d5893f991742464b9e7203c43fc08d0aa11"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-98352","score":0.00161,"percentile":0.05223,"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).
