For SYNC_DIRECT_FROM_DEVICE, it then calls\namdxdna_hwctx_sync_debug_bo(), but passes abo->client.\n\namdxdna_hwctx_sync_debug_bo() uses the passed client both as the handle\nnamespace for debug_bo_hdl and as the owner of the hardware context xarray.\nThose must match the file that supplied args->handle. The BO's stored\nclient pointer is object state, not the ioctl context.\n\nPass filp->driver_priv instead, matching the original handle lookup.","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/216e43d93dd49ec253052741aa476e51a8c54cd8","https://git.kernel.org/stable/c/7caf2a2351d4053075670ff3e26a6815da0a9e1e"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72090","score":0.00165,"percentile":0.05715,"date":"2026-10-31"},"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).
