It also asserts using lockdep\nthat both of those locks are held.  However, the commit I referenced in\nFixes accidentally makes the call to rvt_error_qp in rvt_ruc_loopback no\nlonger covered by r_lock.  This results in the lockdep assertion failing\nand also possibly in a race condition.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","score":4.7},"cwes":["CWE-362","CWE-667"],"references":["https://git.kernel.org/stable/c/43c2d7890ecabe527448a6c391fb2d9a5e6bbfe0","https://git.kernel.org/stable/c/4d809f69695d4e7d1378b3a072fa9aef23123018","https://git.kernel.org/stable/c/57800cc36e55db0547461c49acf5cd84c0f502b0","https://git.kernel.org/stable/c/77ffb2495a41098f9d6a14f8aefde3188da75944","https://git.kernel.org/stable/c/8a50937227c385a477177c9ffa122b4230e40666"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:59:48.811064707+00:00"},"epss":{"cve":"CVE-2022-49089","score":0.00194,"percentile":0.08951,"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).
